multidimensional spectra?

[rabernat]

Thanks for this great package.

I can't quite tell from the docs: does this package support calculation of multidimensional multitaper spectra? For example, if the signal is f(x,y) can it estimate p(k, l), the 2D wavenumber power spectrum?

No this package cannot do it as (last time I checked) the underlying Fortran library cannot do it.

In this paper (https://www.sciencedirect.com/science/article/pii/S0165168497000765) they propose a simple method to construct multidimensional DPSS from 1 dimensional tapers which should be fairly straightforward to implement if you want to give it a shot.
