unified

说明：  to check if two arrays have common element

本程序实现对图像的增强，通过模糊增强算法，使图像的边缘信息更加明显，图像出来，能够更好的处理高频信息(This procedure to achieve an image enhancement, through the fuzzy enhancement algorithm, so that the edge of the image information more clearly, the image out, better able to deal with high-frequency information)

GMM的matalab实现，通过对多个语种进行训练，然后得出每个语种的GMM模型，最终用于语种识别(GMM' s matalab achieved through training of more than one language, then come to the GMM model for each language, and ultimately for identifying languages)

Transient Heat conduction 2d problem with convection boundary condition

本程序是原始粒子群算法，对一个简单函数的优化，可用来与其他算法功能进行比较。(This procedure is the original particle swarm optimization, a simple function of the optimization function can be used to compare with other algorithms.)

用于求一个信号的斜率，通过构造一个滤波器来实现的，绝对正确。(For seeking the slope of a signal, to be achieved by constructing a filter, absolutely correct.)

这是一个二分类器，可以分辨0到9这9个数，并且把1到9分辨为1，把0分辨为0。(This is a two classifiers can distinguish 0-9 number nine, and the 1-9 for a resolution, the resolution was 0 0.)

最小相位系统，混合相位系统，最大相位系统，计算三者的幅频响应，相频响应和冲激相应(Minimum phase system, mixed-phase system, the largest phase system, the calculation of the amplitude-frequency response to the three, with the corresponding frequency response and impulse)

说明：  自己编的线性天线m-file 相信还是有用的(linear antenna)

用MATLAB程序实现卫星位置解算、用户位置解算（最小二乘法）、导航电文读取、坐标转换。(MATLAB program to achieve the satellite position solver, solver user location, navigation message reads, GPS positioning simulation (implemented by the least squares method).)
