ifft2
Two-Dimensionl Inverse Fast Fourier Transform
(y)=ifft2(x)
Inputs
x A two dimensional array of real or complex numbers.
Outputs
y A two dimensional array of complex numbers.


Description
The output of ifft2 is the inverse Fast Fourier Transform of the input. Prior to the computation of the transform, the input is padded with sufficient number of rows and columns with zeros so that both the row-size and the column size of the array is a power of 2.
