You are encouraged to work at the computer as you read thePrimer and freely exp eriment with examples. This Primer, along with the on-line helpfacility, usually suce for students in a class requiring use of MATLAB

PLL锁相环的搭建，通过坐标变换实现锁相(PLL Phase-Locked Loop)

批量tif文件16bit转换为8bit,支持自定义灰度转换(convert 16 bit tif files to 8 bit ones)

Multiple MIMO techniques

自编基于龙格库塔法的Matlab数值积分函数 (Self-compiled Matlab based on Runge-Kutta method of numerical integration of functions)

一些有用的时域有限差分算法的程序合集，涵盖各类边界条件。(Some useful fdtd programs )

cirucular convolution

一个用与电网不平衡的锁相环 是参考搭建的 能够适应基本的不平衡 复杂的情况效果不好(it is used for the unbalanced grid converter and phase locked loop is the basic idea from the id=0)
