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

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

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
<https://help.scilab.org/docs/6.1.0/en_US/size.html>(t,'*');
//number of samples s=sin
<https://help.scilab.org/docs/6.1.0/en_US/sin.html>(2*%pi*50*t)+sin
<https://help.scilab.org/docs/6.1.0/en_US/sin.html>(2*%pi*70*t+%pi/4)+grand
<https://help.scilab.org/docs/6.1.0/en_US/grand.html>(1,N,'nor',0,1);
y=fft <https://help.scilab.org/docs/6.1.0/en_US/fft.html>(s);
Cheers,
Claus
