The following Matlab project contains the source code and Matlab examples used for to compute dft of a given signal . Tracing code is intended to perform N point Discrete Fourier Transform of input signal x. Maximum value of N is equal to signal length. It also computes the DFT matrix of order N.
The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
