My signal is array of numbers captured from sensors.
Like, x=[2 5 3 2 1 4 2 33 45 ] ;
Can I compute the frequency response of this signal using Fourier transform?
Please answer this..
Thank you

Use the fft function.
The documentation explains how to calculate and plot the amplitude and phase spectra. There are also several examples in Answers (many of which I wrote).
