Usage examples about torchkbnufft

[qbit-]

I'm experimenting with audio processing, the entire example is pretty complicated to describe it in full. It would be helpful to have something like the examples on the finufft page here:
minimal interface and the mathematical description of what it does.
By the way, which definition of the NUFFT torchkbnufft supports?

A good self-contained example would be to reconcile against the PyTorch fft module. E.g. check that interpolated points are close to the exact value computed over a finer grid.

Great idea - do you have a specific example that might be useful for people executing 1D NUFFTs? If not, I could just throw something elementary together.

To me this sounds great @kylematoba - just don't have time to implement it right now myself due to other projects... If you open a PR would be happy to consider it!
