gm.11一个简洁的初级学习小程序，希望大家指正，向大家学习(Gm.11a simple primary study of small procedures, we hope that the correction, to everybody study)

基于Matlab的特征提取，图像配准系统的设计，项目完成，实现大场景，多光谱图像的配准。(Matlab-based feature extraction, image registration system design, project completion and achieve big scenes, multispectral image registration.)

误差扩散 FLOYD的使用~~~~~~~~~~(Use of error diffusion FLOYD~~~~~~~~~)

用C-C法求混沌时间序列的延迟时间和嵌入维数，已在MATLAB上验证可用，快速准确，

使读者能对matlab快速上手和熟练掌握操作和应用(Matlab so that readers can quickly get started and master the operation and application)

THIS MATLAB CODE REDUCE THE SPECKLE NOISE IN SAR IMAGE, IT USE WAVELET FILTER THEN USED CASCADE THREE FILTERS IN TIME DOMAIN (HYBRID TIME AND FREQUENCY DOMAIN). THIS CODE NEED SOME MODIFICATIONS SINCE THERE ARE SOME PROBLEMS LIKE BY COMPUTE PSNR AND THE WAVELET HAS SOME ERRORS IN COMPUTE THE DE-NOISING

当线性代数联立方程组的系数矩阵为三对角阵T时，可将T分解为主对角元素为1的下三角阵L和另一个右三角阵R的积。(Simultaneous linear algebraic equations when the coefficient matrix is tridiagonal matrix T, can break down the main diagonal elements of T 1 of the lower triangular matrix L and the other right-triangular matrix R of the product.)

说明：  用牛顿法计算电力系统在级联故障下的潮流，对越限支路进行切除负荷。(Newton method is used to calculate the power flow of the power system under cascaded fault, and the load is cut off for the out of limit branch.)
