What is Fast Multipole Method (FMM) ?

For Non-Equally Spaced Fast Fourier Transform ( NUFFT) the FMM is used for the interpolation of a signal. Can anyone suggest any code or tutorial on FMM and it's implementation for signal approximation? If it possible please give me some idea how FMM can be used for interpolation in NUFFT.

Michael J Rooijakkers

Rick Beatson and Leslie Greengard have written a short course of fast multipole methods, including some semi-code examples. It also contains various citations to the original literature.
