用ICA盲分离的方法，把任意一个声音与噪音进行分离。(Separate a sound from noisy with ICA method.)

这个函数提供灰度拉伸功能，输入图像应当是灰度图像，但如果提供的不是灰度图像的话，函数会自动将图像转化为灰度形式。x1，x2，y1，y2应当使用双精度类型存储，图像矩阵可以使用任何MATLAB支持的类型存储。(This function provides a gray scale stretching function of the input image should be grayscale image, but if not provided, then gray image, the function will automatically be converted to grayscale image form. x1, x2, y1, y2 should use double precision storage, image matrix can store any type of MATLAB support.)

该算法是通过统计图像某一边缘法向方向的灰度变化情况来进行评价。即灰度变化越剧烈， 边缘越清晰， 图像也越清晰。(The algorithm is an edge of the image through the statistical method to change the direction of the gray scale to be evaluated. The more intense the gray change, the more clear the edge of the image are more clear.)

利用MATLAB中的浮点编码编写遗传算法，较为新颖简便。(Using floating-point MATLAB code written in the genetic algorithm, more innovative easy.)

Run the file pathfinder_test.m for a demonstration on how to use the functions.

直方图均衡法的MATLAB图，经过测试没有问题，绝对可以用，做图像的同学可以用来参考.大家可以下载下来在MATLAB中运行试试(Histogram equalization method of MATLAB figure, after test no problem, absolutely, can be used to do image can be used for reference)

基于数值分析方法的多项式最小二乘法拟合，matlab(Polynomial least squares fitting based on numerical analysis method)

说明：  levy飞行改进pso,更好的pso改进措施，大家可以看看(levy_Flight to improve pso)

abc自己编的小程序,呵呵, 可别太认真哦(abc own small addendum to the procedures, what can be seriously oh Do not Consider Too)
