Question

HI, anyone knows how to write a fourier function on matlap ?

Answer 1

HI plasmoduiom,

I dont know why but in matlab always we compute the fast fourier trasform fft. The code is simple.

X=fft(x)

for example

n=-10:10;
x=sin(n);
X=fft(x)

You can find more information at:

or if you type "fourier transform in matlab" into google, you can get a lot of information. The pdf files are very good. Check them out and if you have question ask.
