fft2 (MathScript Function) (Windows, Not in Base Package)
Member of the transforms class.
Syntax
d = fft2(a)
d = fft2(a, b, c)
Description
Computes the 2D 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 fast Fourier transform of a. d = fft2(a) returns the original discrete 2D fast Fourier transform. d is a matrix. |
Examples
A = [1, 2, 3, 4; 4, 3, 2, 1]
C = fft2(A)
