WebI realized that the h returns from ifft is NaN but I don't know how to correct the code. Thanks! Theme Copy load ("AIF_1.mat"); load ("inj_1.mat"); inj_1 = inj (201:2400); inj1_FFT = fft (inj_1); AIF_1 = AIF (201:2400); AIF1_FFT = fft (AIF_1); h_FFT = AIF1_FFT ./ inj1_FFT; h_FFT (isnan (h_FFT)==1) = 0; h = ifft (h_FFT); X = zeros (1,200) 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). ... ifft returns NaN when plotting the impulse response function. 关注 17 次查看（过去 30 天）
