Ifft using fft

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. WebAn 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. I realized that the h returns from ifft is NaN but I don't know how to correct the code. Thanks! Theme.
