ifft1

Calculates the inverse discrete Fourier transform of a matrix using Fast Fourier Transform algorithm.

- - -

Calling Sequence

ifft (x, n, dim)
-ifft (x, n)
-ifft (x)

- -

Parameters

x: -: input matrix
n: -: Specifies the number of elements of x to be used
dim: -: Specifies the dimention of the matrix along which the inverse FFT is performed

- -

Description

This is an Octave function.

Description

This is an Octave function. -The inverse FFT is calculated along the first non-singleton dimension of the array. Thus, inverse FFT is computed for each column of x.

n is an integer specifying the number of elements of x to use. If n is larger than dimention along. which the inverse FFT is calculated, then x is resized and padded with zeros. -Similarly, if n is smaller, then x is truncated.

dim is an integer specifying the dimension of the matrix along which the inverse FFT is performed.
