Package: vision

Compute 2D discrete Fourier transform of input

Syntax

Y = step(H,X)

Description

    Note:   Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

Y = step(H,X) computes the 2D discrete Fourier transform (DFT), Y , of an M-by-N input matrix X , where the values of M and N are integer powers of two.
