    Last Modified: March 15, 2017

    Computes the 2D fast Fourier transform.

    Syntax

    d = fft2d(a)
    d = fft2d(a, b, c)
    Legacy name: fft2

    Inputs

    a

    Matrix.

    b

    Controls zero-padding of the first dimension to the signal. b is an integer and is typically a power of 2.

    c

    Controls zero-padding of the second dimension to the signal. c is an integer and is typically a power of 2.

    Outputs

    d

    2D fast Fourier transform of a. d = fft2d(a) returns the original discrete 2D fast Fourier transform. d is a matrix.

    A = [1, 2, 3, 4; 4, 3, 2, 1];
    C = fft2d(A)
