Fv = linspace(0, 1, fix(length(fft)/2)+1)*Fn; % One-Sided 'fft' Iv = 1:numel(Fv); % Index Vector The fft result to be plotted would then use ‘Fv’ and ‘Iv’ to create an equal-length fft vector. Use the fftshift function to create a two-sided fft result, then: Fv...

what is interpolated dft? How to Get Best Site Performance Select the China site (in Chinese or English) for best site performance. Other MathWorks country sites are not optimized for visits from your location.
And that is indeed an important skill. When you get to the point where you really understand physics, then to a large extent, it becomes easier to translate that understanding into a mathematical model you can work with in MATLAB. To do that though, you will also need to understand MA...
Open in MATLAB Online If you have the original signal as well (before filtering), you can approximate the filter transfer function by taking the Fourier transform of the filtered and unfiltered signals and dividing them element-wise: TrFn = fft(filtered...
