System object: dsp.FFT
Package: dsp

Discrete Fourier transform of input

Syntax

Y = step(H,X)

Description

Y = step(H,X) computes the FFT, Y , of the input X along the first dimension of X. When the FFTLengthSource property is Auto, the length of X along the first dimension must be a positive integer power of two. This length is also the FFT length . When the FFTLengthSource property is Property, the FFTLength property must be a positive integer power of two.
