plotyy.m is not robust. an error occurs depending
on figure with axes is already opened or not.
here is a patch that should solve the problem.

matlab textreads has a "commentstyle" option
where all lines starting with a "#" or "%" or "//"
are commented out when flag is set to "matlab"
or "shell" or "c++" resp. this should be simple to implement.
I gave a try (see patch below) but haven't succeed so far.

> Would you consider coming up with an m-file implementation?
that's a good idea. let me try. just a question:
which Octave's command should I use to read an entire line of
an ASCII file (ie, upto "\n") and put the result in a string?
I don't get this result when doing fscanf(fid,"%s\n",1).

got it: fgetl()

Come build
here is a possible implementation of textread.m:
function res = textread(file, formatstr, prop, val)
if nargin<2
print_usage;
endif
comment_flag=false;
if nargin>2
switch prop
case "commentstyle"
comment_flag=true;
comment_val=val;
endswitch
endif

hi Søren
thanks for the trick with the cell array.
please do your tests with this version instead. it includes
the headerline prop and the '%*' dummy specifier.
those are the basic functionalities of the
original textread we want to have in octave.
the others are kind of gadget, i think.
cheers,

strtrim removes leading and trailing blanks. instead the above line replaces
the occurrence of multiple blanks (including in between fields) by a
single white
perhaps a better option is:
## Deblank string 'str'
regexprep(str,strcat("[",white_spaces,"]+")," ");
-->
if ~isempty(white_spaces)
## Remove multiple white space from string 'str'
regexprep(str,strcat("[",white_spaces,"]+")," ");

hi!
I have been working on exactly the same thing during the last three weeks!
I wouldn't have if I knew that you were about to submit a dedicated package.
I attach my own code to this email. Checking quickly through your code, I
see
that it might be useful to merge part of mine into yours such a
phase implementation with the
advantage that the user can customize its own
anti-aliasing filter.
I have created an account on sourceForge.
please, let me know for the next step.
cheers,
eric.

hi,
I have rewritten resample.m using a polyphase implementation.
See codes attached to this message.
With the test resample_test.m, I compare this code to the current version
of resample.m in OctaveForge. The test consists in
resampling sinusoids of various frequencies and evaluate the disc

hi,
I have finalized the new version of resample.m I proposed last week.
the source is attached to this message. i have made the changes

performed with the "test" utility.

agreed. on the top of that, I think it doesn't make sense to have
this list separated from the other Octave lists. could this list b

hi,
with the following patch, textread.cc returns an empty
matrix rather than an error when reading an empty file
which is, I believe the expected behavior.

I have written a function ( http://www.nabble.com/file/p18490379/fracshift.m

(e.g., a time-series) by a fractional number of samples. this is useful

I've written a routine which computes the Laguerre polynomials.
It could be added to octaveForge? it is maybe redundant with
a routine of the GSL. if it is worth it, I am not sure where it
should be placed (specfun? misc?).

hi,
I have just noticed that not all functions in the SVN repository
are available in signal-1.0.7 on my Debian box. there are functions
(e.g., fracshift.m) that have been included 8 months ago and that
are not part of the distribution. does that mean that the last release
was before 8 months ag
hi,
i have spotted a small misfunctioning of textread.cc
when reading empty files.
$ rm -f test.txt;touch test.txt
$ octave -q
octave:1> [a,b]=textread("test.txt","%f %f")
a = [](0x0)
error: element number 2 undefined in return list
error: evaluating assignment expression near line 1, column 6
#x27;s the best way to act here and I'm CC'ing the
function author Eric Chassande-Mottin. Using a non-integer for shift
value works whether x is column or vector.

This is definetily inconsistent.
