realifft2d (MathScript RT Module Function)
Owning Class: transforms
Requires: MathScript RT Module
Syntax
d = realifft2d(a)
d = realfft2d(a, b, c)
Description
Returns the 2D real inverse fast Fourier transform.
Inputs
| Name | Description |
|---|---|
| a | Specifies a 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. |
Outputs
| Name | Description |
|---|---|
| d | Returns the 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. |
Examples
A = [20, 0, 0, 0; 0, -4+4i, -4, -4-4i]
C = realifft2d(A)
