内有两个MATLAB程序，主要用于语音增强：一个用于向纯净语音文件(wav)添加高斯白噪声，信噪比可选；另一个文件用于测量语音信噪比，对语音增强效果判断(MATLAB, there are two procedures, mainly used for speech enhancement: one for the pure audio files (wav) add white Gaussian noise, SNR optional another document used to measure the voice signal to noise ratio, the effect of speech enhancement judge)

说明：  基于MATLAB的无人飞行器数学模型的飞行仿真实验程序(MATLAB-based mathematical model of unmanned aircraft flight simulation program)

也是利用最小二乘法对椭圆进行数据拟合，不过考虑到图像大小问题，这里只选取100个边缘点，点的个数也可以自行设置。(Ellipse is the least square method of data fitting, but taking into account the size of the image, here select only edge points 100, the number of points you can set your own.)

基于传递函数模型的PID控制matlab代码(PID control based on the transfer function model matlab code)

说明：  基于matlab用神经网络的一组数预测，数学建模里比灰度预测好用(Een reeks nummervoorspelling op basis van matlab met behulp van een neuraal netwerk, wat beter is dan grijze voorspelling in wiskundige modellen)

a perceptron algorithm for neural network

基于对角DCT和2Dpca的matlab人脸识别源码。(right angle based on DCT and the Matlab 2Dpca Face Recognition source.)

In order to minimize power losses caused by high current and improve the voltage profile in the network distribution, the introduction of dispersed generations also called productions decentralized in distribution network (DG) plays an important role. The installation of DGs directly affects the power requested or purchased

说明：  一个进行克里金插值的工具，功能齐全，非常好用(A tool for Kriging interpolation)

实现克里金插值，通过实现matlab实现该方法，可以滤波，并得到比较好的DEM。(Kriging interpolation to achieve, through the realization of Kriging can be filtered, and get better DEM.)
