基于GPU进行快速科学计算，速度远比CPU快得多。这是在GPU上实现FFT运算的程序代码

A very fast FFT for Matlab with GPU

This example solves a 2nd order wave equation: utt = uxx + uyy, with u = 0 on the boundaries. It uses a 2nd order central finite difference in time and a Chebyshev spectral method in space (using FFT). It compares to running the same algorithm on the
