Re: [OctDev] [bug #37616] holidays result incorrect when New Year's Day falls on Saturday

[<lit...@ya...>]

Hi Carnë,

After more careful inspection, it appears that when New Years Day falls on a Saturday, the holiday is not observed at all. The holidays function does not check that, so modifying line 41 will fix that (and also allow holidays to pass its test). So please disregard the previous code change suggestion, and consider the following instead. 

from holidays.m:
------------------------------------------
  ## New Year's Day
  tmphol = datenum (yrs, 1, 1);
  hol = [hol; tmphol(weekday(tmphol(:)) ~= 7)(:)];
------------------------------------------
I modified the last line from 
  hol = [hol; tmphol(:)];

Thanks for the link. I will submit octave-forge bugs there in the future. Should I open up a new thread there for this bug, or is that unnecessary?

Thanks. This belongs in core Octave since that's where the current
implementation of erf and friends is. I would need to modify your
source to fit our style. Besides stylistic issues, there's also the
issue that it should not be a dynamically loaded function, but
built-in, so your wrapper needs to be rewritten. I am happy to do this
myself. Do you have a DVCS somewhere, preferrably Mercurial, where we
could keep your style on one branch and ours in another? Hopefully you
plan to keep working on this function, so it's worthwhile to version
your code. If you don't already have a repository set up, I would be
most pleased to get you started with Mercurial.

Do you recommend replacing the current implementation of erf for real
arguments with your implementation? Currently for real arguments we
rely on the C library's math.h implementation, and for complex
arguments we error out.

Thanks,
- Jordi G. H.

Ok, this does not seem to be an issue anymore.

However, the test of bim3c_tri_to_nodes fails with:

    ***** test
   msh = bim3c_mesh_properties (msh2m_structured_mesh (linspace (0, 1, 31), linspace (0, 1, 13), linspace (0, 1, 13), 1, 1:6));

   assert (un1, un2, 1e-10)

[OctDev] complex error function

[Steven G. J. <st...@al...>]

Hi all, in case there is interest I wanted to let you know that I've 
written a free complex-argument error function in C++ with an Octave 
wrapper at:

	http://ab-initio.mit.edu/wiki/index.php/Faddeeva_w

(This is the Faddeeva function w(z), which is equivalent to erfcx(iz) 
where erfcx is the scaled complementary error function.)  It works for 
arbitrary complex arguments and attains nearly machine precision 
everywhere in the complex plane.  It is under the MIT License, which is 
GPL compatible.

Is there interest in this?  If so, is the right place 
octave-forge/specfun, or ...?

Hi Giorgio

are you able to submit a patch for this? While most of the functions
are written in the very own octave language and should be no problem,
graycomatrix was implemented is written in C++. If you can't fix this,
could you please report this as a bug at
https://sourceforge.net/p/octave/bugs/ so it's not forgotten?

Thanks,
Carnë

This tarball seems to work.

Because of the dependency.  All functions in the bim package that call 
msh3m_structured_mesh are broken, because the later is broken.
