iFit/ifft

PURPOSE ^

c = ifft(a) : computes the inverse Discrete Fourier transform of iData objects

SYNOPSIS ^

function b = ifft(a, varargin)

DESCRIPTION ^

 c = ifft(a) : computes the inverse Discrete Fourier transform of iData objects

   @iData/ifft function to compute the inverse Discrete Fourier transform of data sets
     using the FFT algorithm.

 input:  a: object or array (iData)
 output: c: object or array (iData)
 ex:     t=linspace(0,1,1000); 
         a=iData(t,0.7*sin(2*pi*50*t)+sin(2*pi*120*t)+2*randn(size(t)));
         c=fft(a); d=ifft(c); plot([ a d ])
