Description
Currently the functions nufft2 and nufft3 do not allow for x with a different size from the input function c.
Would the underlying algorithm be compatible with x having a different size with slight changes to the source? Or is it a limitation of the algorithm (NFFT based on low rank approx)?

Research direction
Start by inspecting the implementations of nufft2 and nufft3 and the underlying NFFT-based algorithm. Determine whether inputs x and c can have different sizes, or whether the low-rank approximation imposes a limitation. Done means documenting the constraint or defining and implementing the required behavior.
