Re: octave vs. matlab speed

[Peter Jensen]

Robert,

>From the previous e-mails it appears that 
octave in most cases, is approx 2-3 times 
slower than matlab,

In your case it is 100 times slower !!.

It would be interesting to find out 
what segment of you code that causes
the big difference.

One way to profile your program is 
to insert some tic/toc's. You can then
home in on the offending code.
