In this paper the numerical stability of the matrix-vector product, performed via FFT, is analyzed for the case of the Toeplitz-like matrices. The error appears to depend on the magnitude of the generators of the matrix. The numerical experimentation confirms the theoretical result.

Abstract
In this paper the numerical stability of the matrix-vector product, performed via FFT, is analyzed for the case of the Toeplitz-like matrices. The error appears to depend on the magnitude of the generators of the matrix. The numerical experimentation confirms the theoretical result.File in questo prodotto:
