nufftpy:试验 NUFFT 的纯 Python 实现

# NUFFT in Python This repository holds experiments with pure-python implementations of the NUFFT and related algorithms. For more information see the [NUFFT page](http://www.cims.nyu.edu/cmcl/nufft/nufft.html), and also see the [python-nufft](https://github.com/dfm/python-nufft) package which provides simple Python wrappers for the nufft Fortran source. For a discussion of the Python version of this algorithm, see my [blog post](https://jakevdp.github.io/blog/2015/02/24/optimizing-python-with-numpy-and-numba/) on the subject.
