[OctDev] new packages uploaded and comments on the release procedure / sourceforge website
Hi, published packages I just uploaded the following newly released packages to octave-forge octcdf-1.0.17 general 1.2.0 parallel-2.0.1 the following packages have been submitted for publication but need minor fixes before uploading msh-1.0.0 bim-1.0.0 ocs-0.1.0 fpl-1.0.0 new release system As expected, activating the new web site has spawned the attention required to get the testing started and all the minor glitches that still need to be fixed are being shown, some small things I have noticed: 1) doc strings for class methods get displayed incorrectly see, e.g. http://octave.sourceforge.net/general/function/@dict/dict.html this is because the headers of the html generated by generate_html contains relative links like: which are incorrect in this case as the file is in http://octave.sourceforge.net/general/function/@dict rather than http://octave.sourceforge.net/general/function/ 2) Although I am monitoring the package-releases forum, I expect most users are not and, furthermore, old messages are being automatically purged from that forum, so I think it makes no sense to publish there the news about and release notes for new packages, I'd rather recommend posting such information to this list 3) The NEWS file is not automatically kept in sync with the index page, I'll fix this by inserting a php script to generate the NEWS file as soon as I have time (of course if someone else beats me at this I won't be disappointed) in the index page as soon All the best, c. -- The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com ___ Octave-dev mailing list Octave-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/octave-dev

The only case where a startup time < 3s may matter though is when Octave is being invoked many times within a script. In that case I would say it's better to invoke Octave with the "-qf" option and explicitely load only those packages that are actually needed, e.g. you might want to try this: time octave -qf --eval "pkg load ocs" v.m then try putting all files from ocs into one dir and rerun the test. anyway you should consider that ocs is marked as "Autoload: no" so its presence should not usually influence startup times. > Measuring > the influence of a bigger loadpath isn't as straightforward as startup > time, though.

Surely nothing on the order of seconds. You are right, sorry, I had forgotten about ~/.octaverc.

In case anyone wants to check the results shown in that paper I
prepared a script performing (what is my interpretetion of)
the benchmarks listed in the tables, this could be helpful for keeping
the discussion with the authors on technical grounds rather than
starting a flamewar.
I also reported the results I obtained on my 2.5 years old core2-duo
macbook running OS X 10.5.8 and Octave.app 3.2.3.
My guess is that those guys somehow got a version of Octave linked to
a poor implementation of BLAS/LAPACK

Re: [OctDev] Use of MATLAB Central (was Re: GPL violations)
To add one point of data to this discussion, I just noticed an interesting case that is related to the new TMW ToS: The NURBS toolbox was originally developed by M. Spink and distributed under a GPL v2 license: http://www.aria.uklinux.net/index.php3 I made an Octave package from the NURBS toolbox some time ago and uploaded it on Octave-Forge maintainig the copyright into the original files and the original license, the license is clearly stated as being GPL and the copiright holder as being M. Spink, you can see one example here: http://octave.sourceforge.net/nurbs/function/vecrotx.html I tried to contact the M.Spink at the time I started the Octave-Forge fork of the NURBS toolbox, but his email address seems to be no longer active: http://old.nabble.com/nurbs-package-ts20368543.html#a20368543 The NURBS toolbox was hosted on the Matlab Central Web Site here: http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=312&objectType=file but the link is now broken as the original package was removed probably due to the change in ToS. I just noticed that someone re-uploaded the package on matlab central earlier this year: http://www.mathworks.com/matlabcentral/fileexchange/26390-nurbs-toolbox-by-d-m-spink this latter package seems to be identical to the original version, EXCEPT that 1) The copiright notice has been removed from the file headers 2) The GPL license included in the original version has been replaced by a file named "license.txt" containing a BSD license I beleive this was done to comply with the new TMW ToS, but, as the uploader of the package is NOT the copyright holder, This is clearly in violation of the terms of GPL. Does any of you have suggestions about how to react to this violation? Thanks, c. -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

There is an "an online site with the syntax of function of Octave".
To reach it, just go to http://www.octave.org and click "Docs" on the
menu on the left.
The direct link is: "http://www.gnu.org/software/octave/doc/
interpreter".
The same documentation can be accessed from within Octave by typing
the command "doc"
at the Octave prompt.

It is against the intimate nature of scientific work to present
results that are
in a form that does not allow the community to reproduce them
independently in order
to assess their validity. In particular the information included in
the section on performance
evaluation is vague and incomplete if the code that has been run to
get those timings is not
distributed along with the paper. Indeed, by running what is my
interpretation [attached below in Octave syntax]
of the tests described in that section, I get results that differ by
orders of magnitude to those presented
in the paper. It would be a great contirbution to further development
of free software to make
the code of your benchmark tests publicly available to developers.
Best regards,
Carlo de Falco

sorry, as I said that had not been tested, I had misplaced the 'find'

try the following:

I'm not sure I understand what you want to do, so I am afraid I can't
be of much help here.
What I wanted to say is simply that, if you develop yourself some
algorithms for handling triangular
or tetrahedral meshes that are currently missing in msh, it woul be
very nice if you contribute them to the community.

I see the dataframe package is missing an INDEX file, I added an example INDEX,
please edit it to add more categories if you so deem necessary and try

I didn't mean to say you should remove them, maybe io IS the right place for functions that write vtk files? what I meant is that, given that we have many different functions that save to different vtk file formats, maybe we should chose one single package where they all can be put together. I see different possible solutions and would be interested in hearing somments from others solution 1) putting all vtk-file related functions in fpl which is a package meant to be used for allowing data visualization with external programs solution 2) as many functions to output in third party file formats are in 'io' maybe the vtk functions should also go there solution 3) 'fpl' is composed of 3 different sets of functions: [a] functions to output data in external file formats (.vtu and .dx) [b] wrappers for controlling opendx visualization from within octave [c] wrappers that produce plots in octave's own plotting system with a syntax compatible to matlab's pde-toolbox (pdeplot, pdemesh) so maybe we could get rid of 'fpl' by moving [a] into 'io' removing [b] (as opendx is now obsolete and unmaintained) and moving [c] into 'bim' which is a package similar to pdetool > Nevertheless, I think (some/most/all of) my remarks about style and error > catching still hold (especially error catching as unwary users may have undue > trouble figuring out exactly what went wrong when errors occur).

Usually the policy for accepting functions in octave forge is much less strict than for Octave, usually comments about coding standards like the ones you gave about savevtk are meant as just suggestions, but if some code is useful and works correctly it is usually not rejected because it is not up to the same standards at that of the Octave source code. I am not responsible for this choice, but I think this policy makes sense for attarcting more contributions to OF, once new developers get more involved they will probably take care themselves of cleaning up thei own functions. > We didn't hear from the author (Levente Torok) since several weeks now. > It's sometimes a bit difficult to weigh our own time for tuning scripts sent > in by passing-by users against the usefulness of those scripts. > If they are useful I don't mind putting in some effort; OTOH if the scripts > are of little general use we should invest our time in more urgent stuff. > Someone more knowledgeable in the field of vtk ...dx should have a say > here.

This practice is motivated, among other things, also by an attempt to make life easier for contributors who, like Levente, are wishing to share their code with the community. So, in the case of OF packages, how strictly a function should adhere to coding standards is left to the judgement of the maintainer of the package in which the function will go, and different packages (even if maintained by the same person) may respect the Octave coding standards to a different degree. For example I myself am among the maintainers of both 'bim' and 'nurbs', but while in the former we have tried to stick to the coding standards as much as possible and to use texinfo docstrigs to get a nicer looking documentation, in the latter we decided to use '%' for comments and to avoid texinfo markup as it is a fork from a matlab toolbox and we did not wish to break matlab compatiblity. > If you want your scripts in the io package I could adapt the code > (-style) a bit further for you (and send them to you for review before > committing them), but if you want to retain ML compatibility I suppose > your scripts perhaps should rather be elsewhere in the svn trunk. It seems we all three agreed to some extent that probably 'fpl' is a more appropriate location for 'savevtk', my only concern in that case is to make the name a bit more descriptive to distinguish it from other fpl functions that save in other vtk formats. maybe 'save_vtk_lookup_table' or something similar? > Let me know what you want.

To my knowledge, no other package includes pre-built binaries and I believe this policy makes a lot of sens from the point of view of portability.

Thanks I see, so my suggestion is to just remove the DLL from the package and declare it an external dependency, while to provide windows users with a ready-to-use package you should add your package to the precompiled packages in the windows installer, I think other packages do the same. would that be ok for you? c. -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

Gianvito,
Sorry for the late reply, the package seems ok for me except
for a couple optional cosmetic changes listed below.
As I know nothing about fuzzy logic, I would appreciate comments

1) should probably remove
fl-core-1.0/Makefile

2) you could use better texinfo for the docstrings, for example
itemize lists should use the "@itemize" command rather than be
written manually:

## @item 'min': use the minimum T-Norm (same as fl_intersect(@var{A},@var{B}));
## @item 'prod': use the product T-Norm;
## @item function_handle: a user-defined function as T-Norm.

Yes, you can use the functions from the package FPL to either
- export data to VTK format and visualize it with paraview
('fpl_vtk_save_field')
- plot it directly in Octave ('pdemesh' and 'pdesurf')
if you use the gnuplot graphics toolkit I recommend the first approach as the
second might
become very slow, with the fltk graphics toolkit it is OK though.

OpenDX is somewhat obsolete, the fpl package still has wrappers for it for
backward compatibility,
but I suggest using paraview instead.
Wrappers for Gmsh are in the 'msh' package

This sounds like a problem you have with Octave itself, not with an
Octave-Forge package so you should rather discuss it on
rather than on this list.
Anyway I cannot reproduce your error on my system so it is probably rlated to
your local configuration.

Re: [OctDev] Octave MacOS package, funky or necessary?
Hi, First of all, if you are considering helping in making the Octave OSX binary better, you are very welcome! If you need help with this task you can continue asking questions on this mailing list but, if your questions are about the general Octave build system you will probably more easily find the support you need on or maintain...@octave.org. Also, if you are thinking about building a new binary for Octave you should be looking at a more recent version than 3.2.3, the latest available stable version is 3.4.0.

Hi, It's very good to have tests with your code! Some quick comments after I had a first glance at your code: 1) as it stands, the directory 'tests' in your package will not get installed by the package manager, if one does pkg install fuzzy-logic-toolkit.tar.gz it will just disappear, so most users will never get a chance to notice it ever existed at all. for this reason statements like: "See fuzzy-logic-toolkit/tests/demos/commandline_demo.m" in the help text make no sense, no-one will ever be able to find that file. 2) please consider embedding tests and demos within functions as explained here: <http://www.gnu.org/software/octave/doc/interpreter/Test-and-Demo-Functions.html#Test-and-Demo-Functions> rather than shipping them as separate files. this will also cause the demos to be run automatically when generating docs and the output to appear on the octave-forge website. 3) the copyright notice should not contain the sentence "This file is part of Octave." Octave and Octave-forge are two separate and distinct projects, so a package being hosted in Octave-Forge does not make it part of Octave. You might want to change that with "This file is part of fuzzy-logic-toolkit." or something similar. 4) please consider using texinfo for the help text, it will make the output look better on the command line and it will make it look MUCH better in the octave-forge web pages. you will find enough examples about writing texinfo docstings in other packages on octave-forge. 5) if you don't want to use texinfo, at least remove the "##--" from the beginning and end of each docstring, it is non-standard and looks very ugly when line wrapping occurs. 6) if possible, try to stick more closely to Octave coding standards, as described here: <http://www.gnu.org/software/octave/doc/interpreter/Octave-Sources-_0028m_002dfiles_0029.html#Octave-Sources-_0028m_002dfiles_0029> this is not mandatory, though, as the policy about this in Octave-Forge is much less strict than in Octave. thanks again for your contribution! c. -- Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.

This is because Octave.app was compiled with GraphicsMagick support disabled.
If you want a version of Octave linked to GraphicsMagick you can either compile
it yourself or install MacPorts
<http://www.macports.org/>
and install Octave via MacPorts
<https://trac.macports.org/browser/trunk/dports/math/octave-devel/Portfile>.

I would like to clarify that I don't think multiple return points where the CAUSE of the bug, it is a completely legitimate choice and should work. I just changed the structure to make it easier FOR ME to understand the function flow, and it happened that this removed the error which I, therefore, presume was in one of the lines of code that I changed. Although I did not learn what exactly the error was, as I had a working version of the function I went on and proposed the patch.

The following code works fine for me
#include
DEFUN_DLD (pippo, args, , "test return statement")
{
dim_vector rdims;
rdims.resize (2);
rdims(0) = 1;
rdims(1) = 1;
Cell retval (rdims);
return octave_value (retval);
}
so I still do not understand whee the problem lies.
I'll report back if I have time to look more into this,
but since my interest was in leasqr and not cell2cell itself,
it will be a very low priority task ...

Actually that's what happens in academia, but every now and then I am forced to use Matlab for some industrial project and in such case I get very specific instructions as to which toolboxes I can use and which I cant use. And I don't think Mathworks would ever respond to support requests regarding third-party developed toolboxes. > As such, users don't care if whatever function they use is in > a package or in core, neither in Matlab nor in Octave.

I think that's exactly what a clear separation of the projects intends to avoid. Entry barriers on Octave-Forge are kept low in order to encourage contributions. Not many constraints are imposed in terms of coding standards, generality or matlab compatibility. Most packages uploaded to OF are stuff that someone developed for their own needs and then decided to share with others. If requested to make lots of modifications before committing their code they would mostly just give up. That's not the approach taken in Octave-core where, e.g., matlab incompatibilities are treated as bugs. Do you think it would be an efficient use of resources to have Octave-core developers to take care of complaints about some functions for some very niche application in some forge package being not matlab compatible? The standard response of "that's a function from an OF package please contact the package maintainer" seems like a good way to avoid this. > Basically, all I'm proposing here is that if reduce barriers to entry > and we use a uniform platform for development, we could have very > beneficial cross pollination between Octave and 'Forge.

Re: [OctDev] Questions about BIM

First of all, BIM is a package from Octave-Forge, it is
not part of the core Octave project, so the correct place where
to discuss this matter is the Octave-Forge mailing list, so I am moving this
thread there.

The title of the book you cite says it all,
"Numerical Solutions of TIME DEPENDENT Advection Diffusion Reaction Equations"
while the tutorial deals with a steady state DAR equation
> I do not see this tutorial progressing through time. Am I correct?
Yes, the extension, though, is quite trivial.
For example, given the equation
du/dt - d/dx (D du/dx - C u) + R u = f 0 < t < N*T
after time semi-discretization with implicit Euler method and a fixed time-step
T becomes
- d/dx (D d u_i /dx - C u_i) + (R + 1/T) u_i = f + u_{i-1} / T,i = 1 ... N
which is a sequence of steady state DAR problems, so once you are able to solve
steady-state
you are able to solve time-dependent as well.
If you'd like an example using more advanced time stepping techniques I have
quite a few using DASPK
for fully-implicit adaptive time-stepping, but I never added them to the
repository because I do not
have time to write documentation for them.

Actually, I don't think we necessarily need ONE leader but rather more motivated and active contributors.

The rule of thumbs is usually to add to core Octave those functions that are core Matlab functions and to Octave-Forge those that are in some toolbox. Also, as Jordi already said before, to be included in the core Octave distribution, functions must comply to the Octave coding standards, while the requirements are much less strict for Octave-Forge. It is not clear from your mail where you want these functions to go, you sent the functions to Octave-forge mailing list but you mention locations that are in the Octave-core source tree, could you please be more specific. >> Please let me know where they are placed, for the reference. > > Hi, > > I'll commit the functions tonight or tomorrow unless someone reviews > them negatively. > > Carnë Carnë, where do you intend to put these functions? The OP suggested locations that are in Octave-core, not some package in Octave-Forge.

It would be great to even have automatic SVG to geo conversion! one could then draw a geometry with his/her favourite drawing program and use it as input for msh ... c. -- All the data continuously generated in your IT infrastructure contains a definitive record of customers, application performance, security threats, fraudulent activity and more.
