@OtacilioNeto

Dears, when I run this command on a scilab running on freebsd compiled with openblas I get a time of 37 seconds
A1=rand(1000, 1000); tic();[S, v, D]=svd(A1);toc()
ans =

37.276 

The same command on windows with intel library I get 1 second

A1=rand(1000, 1000); tic();[S, v, D]=svd(A1);toc()
ans =

1.382  

Could you please give me a hint why is so different?
