Hello,
Any comments to the pasted mini-benchmark results Octave vs. Matlab? Matlab
6.x relies strongly on Atlas when it comes to multiplication of matrices. I
have heard that this is also the case with Octave. Why are the results
(computation times) so different?
>>ver
MATLAB Version 6.5.0.180913a (R13)
>> A = rand(500,500);
>> tic, B = A*A; toc,
elapsed_time =
0.7135
octave:13> version
ans = 2.1.36
octave:14> A = rand(500,500);
octave:15> tic, B = A*A; toc,
ans = 8.4542
Best regards,
Zdenek Hurak
