屏幕上不停地出现随机（随机颜色，随机边长，随机线宽）的三角形(Constantly appear on the screen randomly (random color, random side, random width) of the triangle)

对二维图像实现巴特沃斯低通和高通滤波，已经仿真，效果不错。(Pairs of two-dimensional image realization of Butterworth low-pass and high-pass filtering, has been simulation, good results.)

this is very good for master students and use in communication system course

说明：  用分布傅里叶计算非线性薛定谔方程，改自《非线性光纤光学》第五版。(Calculation of the nonlinear Schrodinger equation with the distributed Fourier)

关于空域滤波的实现 包括几种算法的实现 很好(nksakh)

加窗傅里叶变换（windowed fourier transform_guassian）取hanning窗。(Windowed Fourier transform (windowed fourier transform_guassian) take hanning window.)

一篇论文《MATLAB语言在天线设计中的应用》包含天线的二维和三维方向图的绘制方法及源程序(Paper " MATLAB language in the antenna design," contains two-dimensional and three-dimensional orientation of the antenna mapping method and source)

用matlab对对象进行了模糊PID的编程。(The fuzzy PID programming on object using matlab and VC language. )
