FFT in MATLAB

[Ruudje]

Hi all,

I would like to do a FFT in MATLAB. I have two vectors, one time and the other the actual signal. How can I do this?

Another problem I hav is how do I get a overline in a label? Tried using Latex code but I'm not sure how to use it.


Greetings

PS Using matlab 7.4.0 (R2007a)

Have you looked at the matlab help page for the fft function. It has an example of exactly what you are trying to do.

I like this tech note provided by The MathWorks:

thanks all of you, I already saw that specific tech. It uses a frequency as the time input while I have a vector with timestamps. I'll try to rewrite it.
Can anybody help me with my Matlab LaTeX compatibility? basicly I want to hev a Latex formula in the ylabel.

regards, Ruud
