几种常用求逆的Matlab程序,在一个博客中找到，分享一下(Several commonly used inverse of Matlab procedures, found in a blog, share)

heat equation cranknicolson

非局部中值滤波 matlab代码,主要用于图像去噪，对于存在周期出现的图像有较好的效果，例如干涉图(Nonlocal median filter matlab code. It is mainly for image denoising and images with the existence of cycles are correspinding to good results, for example interferogram.)

simulation of neural network for adaptive control

粒子群算法优化支持向量机的惩罚参数c和rbf的参数gamma。(Particle swarm optimization (PSO) optimizes the penalty parameters c and RBF of SVM gamma.)

对需要分析的振动信号进行预处理，消除趋势项(To deal with the vibration of the signal preprocessing, eliminate trend)

说明：  支持向量机回归用于电力系统短期负荷预测，内包含.m程序和数据(Support vector machine (SVM) regression is used for short-term load forecasting of power system, including. M program and data)
