[Octave-bug-tracker] [bug #34893] Unexpected and inconsistent conv/conv2 results

[Rik]

Update of bug #34893 (project octave):

                  Status:                    None => Confirmed

Follow-up Comment #4:

I have confirmed these results on the latest available Mercurial tip.  This
bug report is for 3 different issues:

1) conv() does not support the shape 'valid'
2) conv2 produces different results for shape 'valid' depending on the
orientation of matrix B.
3) conv2 picks the wrong part of the convolution for shape 'same'

I have already coded a patch for item 3.  Alas, it will probably not make it
in to release 3.6.0.

Issue 2 is caused by some deep problem involving how Octave is calling Fortran
code.  I'm not touching that problem for now.

For issue 1, I would like to see the Matlab's interpretation of the following
two commands.  If the original reporter, or someone else, can supply that then
I can finish off issue 1 as well.


conv (1:2, 1:5, 'valid')
conv (1:5, 1:3, 'valid')
