C语言实现图像的快速傅立叶变换，离散傅立叶变换。环境是CVI，一个与硬件快速接口的软件。-FFT，fast fourier transit

基于lapack和blas开发的线性代数开源库，可实现矩阵基本操作，函数接口与matlab类似，容易上手，相同硬件环境运行速度仅为matlab的1/5.-Linear algebra library LAPACK and Blas based development, can realize the basic matrix operations, similar to the matlab function interface, easy to use, the same speed hard
