Dear Octave maintainers,
Recently in an experiment I found that for sparse X'*v octave seems to do X'
first and then conduct the matrix vector product. This is time consuming as
this operation is simple a linear combination of X's columns and X in Octave is
stored in compressed column format. May I suggest that you improve the setting
in the near future?
Thanks,
Chih-Jen
