izak

Purpose

Inverse Zak transform.

Synopsis

sig = izak(DZT)

Description

izak computes the inverse Zak transform of matrix DZT.

Name	Description	Default value
DZT	(N,M) matrix of Zak samples (obtained with zak)
sig	output signal (M*N,1) containing the inverse Zak transform

Example

If we compute the discrete Zak transform of a signal and apply on the output matrix the inverse Zak transform, we should obtain again the original signal:

         sig=fmlin(250); DZT=zak(sig); sigr=izak(DZT);
         plot(real(sigr-sig));
