Hello Wei,
thanks for your answer to my question.
The point now is: I am working with huge matrices (at least 1024x1024,
typically 5000x3000, at most 7000x5000).
In this case you say that Matlab is faster than GSL ?
How about for loops? Do you think Matlab can run loops faster than C
language?
I do need loops to solve my problem which is a kind of exhaustive test
for error probability.
Have you test memory charge also? I guess Matlab is so memory consuming.
Again, thank you very much for your help.
Cheers,
Robinson
