Package: octave-common
Version: 3.6.2-5
Dear Maintainer,
The function "interpft" has a problem when used for downsampling a vector.
The following octave code triggers the problem:
octave:11> clear
octave:12> y=zeros(100000,1);
octave:13> yi = interpft(y,31000);
error: reshape: can't reshape 33334x1 array to 31000x1 array
error: called from:
error: /usr/share/octave/3.6.2/m/general/interpft.m at line 86, column 7
The function works correctly in squeeze. I believe the problem to be at the
line 71 of this interpft.m:
inc = max (1, fix (m/n));
This line replaced a while loop in the squeeze version but the new version
gives a wrong result when downsampling. Replacing this line with
inc = ceil (m/n);
solved the problem for the tests I ran. I believe this bug is also
present in the version 3.6.4-1 in experimental since the file
interpft.m is the same in both versions AFAICT.
Best wishes,
Ubiratan Freitas.
