WebWhen z contains an array, fft computes and returns the multivariate (spatial) transform. If inverse is TRUE , the (unnormalized) inverse Fourier transform is returned, i.e., if y <- fft (z), then z is fft (y, inverse = TRUE) / length (y). By contrast, mvfft takes a real or complex matrix as argument, and returns a similar shaped matrix, but ... http://stm32f4-discovery.net/2014/10/stm32f4-fft-example/
