For compression
Octave uses '-z' or '-zip' options
MATLAB uses '-compress' or '-nocompress' options
presumably Octave uses no compression by default. MATLAB compress options only
apply to '-V7' or '-V7.3' formats.
I did a test where I save'd a file in Octave with '-zip':
====== begin script ==================
A = eye(5,5);
save('test.mat', A, '-V7', '-zip');
====== end script ==================
I asked a friend who has MATLAB to open and they were able to successfully
open the file. This seems to indicate that MATLAB also uses gzip compression.
So my request is this: can Octave save function be modified to include
'compress' and '-nocompress' options to improve compatibility?
