Re: [Scilab-users] scilab mkdir and UNC path support

Hi all,

The lack of support for UNC path in scilab is a real issue in our lab (UNC path 
are Windows paths that looks like \\server\dir1\subdir1\).
In particular it breaks atomsInstall for all the Windows users here as our home 
dir is mounted as a UNC path: \\servername\username.
I found the main issue (I think) in mkdir() at line 88:
 subdirs = strsplit(NewDirectory, ["/" "\"]);
obviously, splitting the  path to the new directory is not going to give you something 
nice with a UNC path that starts with "\\".
I have an idea to workaround this limitation, but there is still something I don't get in 
the logic of mkdir(): this splitting is associated with "bAddFirstDirSep", a 
variable that tries to detect something wrong with the first directory separator.
Could anyone more knowledgeable than me explain why it is there and what is is 
doing?
I would not want to reintroduce some bug with my modified version...


On windows, we have
--> pathconvert("c:\",%f,%t,"u")
 ans  =
 /cygdrive/c

I don't know what we might do with this. There is no cygdrive on my 
computer (AFAIK :/)


Conversely, could you try something like
--> pathconvert(your_slashslash_path, %f, %t, "w")

Re: [Scilab-users] ?==?utf-8?q? Unable to update ATOMS packages - Scilab 6.0.1

[Antoine Monmayrant]

Hello,

Here is what I did in Ubuntu 18.10 to get scilab 6.0 nightly build to work (it 
also suffers from the missing libgfortran): 
- download the last nighlty build of the 6.0 branch,
- untar it,
- sudo apt-get install libgfortran3,
- run scilab from the terminal,
- success!

Could you use the same approach to solve your problems?

Antoine

Re: [Scilab-users] uicontrol TABLE

[Izabela Wójcik-Grząba]

I am not getting any error message. I tried also not to close the 
window. How should it work? It's unclear for me.

If you really do things in this order, you kill the uicontrol that
can't be addressed anymore, and you should get an error message:

--> t2=matrix(ut.string,size(table))
at line 7 of function %h_e ( SCI\modules\graphics\macros\%h_e.sci 
line 19 )


get: The handle is not or no more valid.

and then yes, t2 has not been updated.


The table t2 is unchanged. Maybe I am doing something wrong?

Aa, you might also have considered that after
t2=matrix(ut.string,size(table))
your t2 always points to the table's content, and that each modification 
in the table updates it automatically.
It's the case for ut.string, but not for t2. To update t2, you still 
have to rerun

t2=matrix(ut.string,size(table))

Hello Izabela,

Hello,

Sorry for returning to the topic of editting uicontrol Table but I still
don't know how it works. When I change the data in a Help example (code
below) the resulting table t2 doesn't change.


You are likely using Scilab 5.5.2. This bug is fixed in Scilab 6.

Re: [Scilab-users] Tall Array in Scilab

[CRETE Denis]

Hello,
Did you try to increase the stack size with stacksize() ; it may be a simple 
solution if the array is not too big.
Otherwise, I generally recourse to the Scilab function unix_g(), with a string 
parameter calling one of the basic OS functions (e.g. sed or grep) to reduce 
the size of the array before processing with SciLab.

Objet : [Scilab-users] Tall Array in Scilab

Hello M'ms and Sirs,

Do we have the concept of Tall Array in scilab, because I need to read a big 
chunk of data and it may get worst and worst soon and scilab is crushing 
because it cannot handle it.
The concept of Tall Array is explained it here 
https://www.mathworks.com/help/matlab/import_export/tall-arrays.html


So if anyone can help it will be very helpful ?

Thanks in advances.
