The advantage of this method +is that there is little or no overhead in the generation of the plan, which is appropriate for a Fourier transform that will be calculated once. + + +"measure" +In this case a range of algorithms to perform the transform is considered and the best is selected based on their execution time. + + +"patient" +Similar to "measure", but a wider range of algorithms is considered. + + +"exhaustive" +Like "measure", but all possible algorithms that may be used to treat the transform are considered. + + +"hybrid" +As run-time measurement of the algorithm can be expensive, this is a compromise where "measure" is used for transforms up to the size of 8192 and beyond that the "estimate" method is used. + + +The default method is "estimate".

The default is the length of the "window" vector or has the same value as the scalar "window" argument. If Nfft is larger than the segment length, "seg_len", the data segment is padded with "Nfft-seg_len" zeros. The default is no padding.

Power from negative frequencies is added to the positive side of the spectrum, but not at zero or Nyquist (Fs/2) frequencies. This keeps power equal in time and spectral domains. See reference [2]. 'whole', 'twosided' : frequency range of the spectrum is -Fs/2 to Fs/2, with negative frequencies stored in "wrap around" order after the positive frequencies; e.g. frequencies for a 10-point 'twosided' spectrum are 0 0.1 0.2 0.3 0.4 0.5 -0.4 -0.3 -0.2 -0.1 'shift', 'centerdc' : same as 'whole' but with the first half of the spectrum swapped with second half to put the zero-frequency value in the middle. (See "help fftshift".
