X'*v in octave

[Chih-Jen Lin]

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,
