计算psnr，普通的4:0:0或者灰值图 有范围判断(calculate psnr format 4:0:0 or gray value picture judge for range)

电力系统中导纳矩阵的形成,用于计算潮流,比较重要(power system admittance matrix formation used in the calculation of the trend, the more significant)

这是一个MIMO信道容量的计算。使用SVD分解和注水定理。(This is a MIMO channel capacity calculations. Using the SVD decomposition and water-filling.)

基于SVR的非线性系统的辨识和校验，辨识信号为幅值为2的随机信号(Nonlinear systems based on SVR identification and validation, identification signal is a random signal amplitude of 2)

Simulation for sampling of frequency

This function used for calculate ellipse point to draw.

解决图匹配的二次规划问题，完成一对一的匹配(Solve quadratic programming graph matching problem, and to complete a one-to-one matching)

包括最小二乘法、SVM、神经网络、1_k近邻法,BP神经网络用于函数拟合与模式识别，在MATLAB中求图像纹理特征，代码里有很完整的注释和解释，通过反复训练模板能有较高的识别率。(Including the least squares method, the SVM, neural networks, 1 _k neighbor method, BP neural network function fitting and pattern recognition, In the MATLAB image texture feature, Code, there are very complete notes and explanations Through repeated training jLKGpfTlate have higher recognition rate.)

Vertical Lines detection

说明：  matlab的入门学习好帮手，我看了后学到了很多，希望和大家共享。(Matlab to learn good helper, I watched a lot of deconstruction, hoped and everybody sharing.)
