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 ]) Version: Nov. 26, 2018 See also iData, iData/fft, iData/conv, FFT, IFFT
