Use of NFFT

[dashingdiggi]

Dear Sir,

I recently started working on NFFT. I Have a really basic question about this package, please excuse me for that.
I have irregularly sampled data in the time domain. Can I compute its spectrum using NFFT.jl? As I can see in the algorithm, NFFT requires data to be sampled regularly in any one of the domains. I really appreciate any help you can provide.

Thank you.

That question is not so basic actually. I have some comments about it here:

I would recommend using density compensation if you want to pursue this.
