how to improve the speed of octave?

[frank wang]

Hi,

 

I am trying to use octave for a big project. It is written in matlab. When I run the code on octave, it is significantly slow. The code involes a lot of fft operation. I have compiled the octave 2.9.8 by myself. How can I compile the octave to make it run faster? Do I need to install Atlas, fftw3, blas, lapack or other packages?

 

Thanks
