They are from open source Python projects. ulab is inspired by numpy. The only differences between the manual spectrogram that we created versus the SciPy's built-in function are that SciPy returns the spectrum magnitude squared (which turns measured voltage into measured energy), and multiplies it by some normalization factors. Tracing the exact origins of the Fourier transform is tricky. python image algorithm matlab image-processing asked Apr 9 '15 at 23:26 Efficiently compute a 3D matrix of outer products - MATLAB What is a spectrogram and.
