what is the inverse function (inufft??) of non uniform version Fast Fourier transform(nufft)?

Hi guys,

I would like to ask the N-D inverse non uniform Fast Fourier Transform (inufftn). It seems that inufftn is still in the air.

Looking forward hearing from you guys!

Hi,

As per the MATLAB release 2023b, the function "inufftn" does not exist. However, you can refer to the following MATLAB answer to get an idea on how to implement it:
