matlab经典算法的程序（优化 绘图 解方程 数据分析等等）(matlab program of classical algorithm (optimized mapping equations data analysis, etc.))

This matlab code describes Perturbation and observation algorithm for calculation of maximum power point of a PV module. It is a basic example.

增广矩阵最小二乘法，用于处理数学建模及系统辨识中的一些问题(Augmented matrix least-squares method for handling mathematical modeling and system identification problems)

this is an implementation of snake in 3D

说明：  利用差分法，将数据拟合，从而可以更好的辨识非线性系统的损失位置。(By using the difference method and fitting the data, the loss location of the non-linear system can be identified better.)

Read video frames into matlab using avisynth, or retrieve an info struct with information about the video. Input can be a video, an avisynth file or a cell-array of avisynth commands.

说明：  波模极大值实现对图像的边缘检测 wavelet modulus maxima edge detection

matlab编写的随机森林算法，网上下的，拿来分享一下(Random Forest algorithm, matlab prepared online, and brought it to share)
