Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 Here are a few comments on the use of PlainFFT. First of all: PlainFFT performs in place calculation, which means that the results are recorded within the vectors containing the source data. “Usable” results are available on completion of the ComplexToReal() execution. Before execution, vReal and vImag vectors contain the transformed results from the […]
