Discrete Fourier transform

Usage

Jacket for M Language

Supported Syntax

Y = fft(X)
Y = fft(X,n)
Y = fft(X,[],dim)
Y = fft(X,n,dim)

GFOR Supported	Yes
GCOMPILE Supported	No
Types Supported	- GDOUBLE GSINGLE COMPLEX
Types Not Supported	- GLOGICAL GINT32 INT8 GUINT32 GUINT8
CPU usage	Jacket only contains GPU computing functions. To run functions on the CPU, try one of the MathWorks products: http://www.mathworks.com/access/helpdesk/help/techdoc/ref/fft.html

The syntax fft(X,N,DIM) is presently supported only if DIM matches the first non-singleton dimension of X.
FFT limited to inputs with less than 135 million elements
