http://mirrors.ibiblio.org/grass/code_and_data/grass82/manuals/i.ifft.html WebHello, I seem to be having issues using MATLAB's fft and ifft functions. An impulse response function h(t) has the following formula: inj(t) * h(t) = AIF(t). We know that the graphs of inj(t) and AIF(t) are as followed. I wrote the following code to do the deconvolution but h(t) in the output graph is zero.
