Matlab, How to get frequency spectrum? - Forum for Electronics I am uploading 2 PDF files on Fourier Transform / Spectrum calculation and display in Matlab. I used it for the lab of DSP. You can also use the below function for displaying the frequency spectrum in MATLAB. As "N" the number of points for fft increases
