# fft2d

Version:

Computes the 2D fast Fourier transform.

## Syntax

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

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.

## 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)
