WebCreate and plot 2-D data with repeated blocks. Compute the 2-D Fourier transform of the data. Shift the zero-frequency component to the center of the output, and plot the resulting 100-by-200 matrix, which is the same size as X. Pad X with zeros to compute a 128-by-256 transform. Y = fft2 (X,2^nextpow2 (100),2^nextpow2 (200)); imagesc (abs ... WebApr 13, 2024 · fftfreq - get exact Matlab FFT frequencies. Calculates the exact Fourier frequencies for spectra calculated via FFT. This functionality is not provided by Matlab, hence requires custom function. Currently only works on vectors/1D arrays. It is not straightforward due to how the operation is done on a bit-level.
