[Scilab-users] fft

[Claus Futtrup]

Hi there

The 2D example from the help pages also crashes Scilab.

Maybe my Scilab installation is broken - the FFT part? I can't remember, 
but I think I installed the Intel Math Kernel with everything. My 
computer is a Lenovo T480 with Intel Core i7 processor. I have the 
following installed:

C:\Program Files\scilab-6.1.0>dir /S /B fft*.*
C:\Program Files\scilab-6.1.0\bin\fftw
C:\Program Files\scilab-6.1.0\bin\fftw.dll
C:\Program Files\scilab-6.1.0\bin\fftw\fftw-readme.txt
C:\Program Files\scilab-6.1.0\modules\fftw
C:\Program Files\scilab-6.1.0\modules\fftw\etc\fftw.quit
C:\Program Files\scilab-6.1.0\modules\fftw\etc\fftw.start

Cheers,
Claus
