# realifft2d

Version:

Returns the 2D real inverse fast Fourier transform.

## Syntax

d = realifft2d(a)
d = realfft2d(a, b, c)

Matrix.

## b

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

## c

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

## d

2D real inverse fast Fourier transform of a. d = realifft2d(a) returns the original discrete 2D real inverse fast Fourier transform. d is a matrix.

A = [20, 0, 0, 0; 0, -4+4i, -4, -4-4i];
C = realifft2d(A)
