IFFTREAL - Inverse FFT for real valued signals

Usage

f=ifftreal(c,N);
f=ifftreal(c,N,dim);

Description

ifftreal(c,N) computes an inverse FFT of the positive frequency Fourier coefficients c. The length N must always be specified, because the correct transform length cannot be determined from the size of c.

ifftreal(c,N,dim) does the same along dimension dim.
