图像的旋转变换的matlab程序，里面有程序的运行结果，附带图片(matlab correction image)

通过pca找点云主方向，确定新坐标，然后将旧坐标点投影新坐标(Coordinate transformation using Principal Component Analysis)

MIMO OFDM matlab仿真,针对EMD方法的不足,esprit算法对有干扰的信号频率进行估计。( MIMO OFDM matlab simulation, For lack of EMD, esprit algorithm signal frequency interference can be assesse.)

optiFDTD计算MIM波导缺陷结构，这是源文件

随机数的产生！ 在matlab里面实现的(The generation of random numbers! Inside achievable in matlab)

说明：  为了了解地震波的传播，用有限差分对二维声波传播进行模拟(Solving wave wave equation with finite difference)

能够见汉字转为拼音，并且速度很快，可以很好的将文字进行转化(脛脺 鹿 禄录 没 潞 潞 脳 脰 脳 陋 脦 陋 脝)

说明：  二维的仿真，入射波为空间高斯型，入射到一个单狭缝上透射情况。金属介质为Drude模型(Two-dimensional simulation, the spatial Gaussian incident wave, incident to a single slit on the transmission case. Medium for the Drude model of metal)

matlab实现具有混沌特性的Lorenz系统的二维三维图形(matlab implementation of the Lorenz chaotic system with two-dimensional three-dimensional graphics)

主要是利用归一化的方法进行位场边界识别，利用导数与周围最大值的比值来进行。(Mainly using the method of normalized potential field boundary identification, the use of derivative and the ratio of maximum to be around.)
