fftcoeffs

Frequency-domain coefficients

Syntax

c = fftcoeffs(hd)

Description

c = fftcoeffs(hd) return the frequency-domain coefficients used when filtering with the dfilt.fftfir object. c contains the coefficients

Examples

This example demonstrates returning the FFT coefficients from the discrete-time filter hd.
