MATLAB provides an internal fft function. The command cds_fft calls the internal MATLAB fft function. It prepares the input signal, and calls fft for each outer sweep. The command is fsig = cds_fft(tsig) The input parameter tsign is a time-domain signal. huws gray horncastle

"A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). Fourier analysis converts a signal from its original domain (often time or space) to a representation in the frequency domain and vice versa. The DFT is obtained by decomposing a sequence of values into components of different frequencies. This operation is useful in many fields, but computing it directly from the definition is often too slow t… " - Spectre fft
