You can use scipy.signal tutorial and reference guide in most cases, but
|
|
there are some important differences:
|
|
* input data is assumed to be complex and two-sided spectrum is always returned
|
|
(return_onesided argument is not implemented)
|
|
* length of FFT is always same as length of segment (nfft argument is not
|
|
implemented)
|
|
* functions work always over last axis of array (axis argument is not
|
|
implemented)
|
|
* if you want to have best FFT performance with pyFFTW, you should create arrays
|
|
with empty, zeros or ones functions from SimpleSpectral instead of generic
|
|
versions from NumPy (arrays will be byte aligned for your CPU)
