Hi Scilabers I'm trying to understand how to use the FFT function in Scilab. I'm using v. 6.1.0 on a Windows 10 machine. This crashes Scilab:y = linspace(1,256,256) x = fft(y) BTW, the example in the online help (https://help.scilab.org/docs/6.1.0/en_US/fft.html) also crashes Scilab:
sample_rate=1000;
t = 0:1/sample_rate:0.6;
N=size(t,'*'); //number of samples
s=sin(2*%pi*50*t)+sin(2*%pi*70*t+%pi/4)+grand(1,N,'nor',0,1);
y=fft(s);
Cheers,
Claus

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

Claus, I recall that I had had a similar problem in certain occasion. The reason was that when installing Scilab I had selected an option to use a version of the FFT which, since it was much larger, I thought would be more complete, or faster... but it didn't work. Try to re-install Scilab and choose the default version of the FFT engine. It is good enough... and works! Regards, Federico Miyara On 26/11/2020 15:24, Claus Futtrup

Hi Federico
Thank you for your advice. I guess
reinstalling Scilab is what I need to do.
Best regards,
Claus
