FFT可以将一个信号的频谱 提取出来，这在频谱分析方面也是经常用的。 (A signal can be extracted from the FFT spectrum, which spectrum analysis is also often used.FFT)

This function is equivalent to matlab fft2 function, but without using for loops, instead this function is implemented using matrix multiplication.

包括matlab中一些常用的函数，还有一些特殊函数，如马库姆函数(marcum Q-function)

upsampling and downsampling

this code is use do create 3d structure of 3d object

一种优化蚁群算法 只要改一下参数就可以实现您的计算效果(An ant colony optimization algorithm)

说明：  在多个特征中选取敏感特征，可以降低特征集的维数，提高分类准确率(Select the sensitive feature in multiple characteristics, can reduce the dimension of feature set, improving the classification accuracy )
