standard code for PSO

This function stretch and scale the histogram

Matlab pfile for converting a binary image boundary to a 4-connected boundary.

图像边缘检测及分割的matlab实现，有好几种方法，可以都学习一下(Image edge detection and segmentation of the matlab implementation, there are several ways you can both learn about)

说明：   Buck－Boost电路的建模与仿真主程序

说明：  对比了dv-hop基本算法，和加入pso后得算法。由于结果是随机产生的，不能保证每次得结构都能提高，但大部分时候，比基本算法得定位准确度好。(DV hop algorithm is compared with PSO algorithm. Because the results are generated randomly, it can not be guaranteed that every time the structure can be improved, but most of the time, the positioning accuracy is better than the basic algorithm.)

Generates a lognormally faded signal with multipaths (10) and multiple scattering (5)

偏最小二乘法是一种数学优化技术，它通过最小化误差的平方和找到一组数据的最佳函数匹配。 用最简的方法求得一些绝对不可知的真值，而令误差平方之和为最小。(Partial least squares method is a kind of mathematical optimization technique, it through the minimum error sum of squares to find a set of data the best function matching. With the Jane s method for some absolutely unknowable true value, and make the sum of error square to a minimum.)

matlab阵列信号处理工具箱DBT,版本2.20,阵列信号处理必备(Directory stored in the source wavelet coding, including the commonly used wavelet transform procedures for)

说明：  基于背景差分法和帧间差分法的目标跟踪 应用了二维滤波，效果较好-(Application of a two-dimensional filtering, target tracking based on background subtraction and interframe difference method better)
