fourier_by_jump is a fourier analysis, especially made for sampled data, but it is not a DFT. FOURIER_BY_JUMP is a fourier analysis, especially made for sampled data, but it is not a DFT.The function assumes equidistant sampling and only one full period of the fundamental. If the function is used on N fundamentals, the harmonics are shifted to N*f. The function does not work on non-integer numbers of fundamentals.The reason for writing this function is that Matlab's own internal fft-function occational gives results that are un-satisfying especially when regarding sampled PWM-voltages. The function is a true fourier analysis, not a FFT or a DFT analysis. The function is optimized for speed, but it is possible that it may be made faster by eliminating the remaining for-loops.The function is tested on Matlab v 5.3. Requirements: · MATLAB Release: R11
