A DFT matrix is an expression of a discrete Fourier transform (DFT) as a transformation matrix, which can be applied to a signal through matrix multiplication.
If the size of the DFT matrix is increased without bound, it approaches the Fourier operator that defines the continuous Fourier transform.
