This should work if you precise the nfft
argument and you use a number larger than your dataset dimensions, as done in dask.array.fft
I 've just noticed that nfft
is missing in the current docstring of xscale.fft.fft
. This should be corrected and mentioned in the documentation. If you're willing to contribute to the documentation, it will be very welcome !
I have also implemented fitting methods xscale.signal.fitting
but they require more work as
You should be able to remove a linear trend on multi-dimensional dataset using xscale.signal.fitting.detrend
. These functions require however additional testing.
ok, great. I know the nfft argument from the scipy.signal package but i had not seen it in your doc indeed. I will test this and try to contribute to the doc asap.
I haven't tried any detrending methods yet as my current dataset is already detrended, but yeah, i'll let you know when i have used/tested it.
Hi Guillaume, I am using your fft routines. Very convenient to process gridded data! Just wondering if you have implemented yet some option to pad with zeros both ends of the data before performing the fft?
