这是一个关于BPSK在高斯信道的仿真程序，仿真最后给出BPSK在高斯信道的信噪比 误码率曲线(This is a BPSK in Gaussian channel on the simulation, emulation BPSK given the signal to noise ratio in Gaussian channel bit error rate curve)

GSMK的仿真高斯最小频移键控GMSK信号同相分量波形 (Gaussian Minimum Shift Keying)

数字PID的matlab仿真程序，针对刘金琨的先进PID控制的matlab仿真，里面的部分程序进行了修改 第三章(Digital PID of matlab simulation program for Liu Jinkun matlab advanced PID control simulation, which part of the program were modified Chapter)

自己编的最新的gquad方法，非常的好用(Own series the latest gquad method, very easy to use)

凸包绘制源程序Matlab的实现,凸包Matlab绘制(Convex hull draw Matlab source implementations)

直角坐标转换到极坐标下代码，以图像中心为原点，水平向右为0°方向，顺时针旋转生成极坐标图像。(converts a given image from cartesian coordinates to polar coordinates.)

源码，非常实用，里外都是经过上机调试的源码，可以直接使用！(Source, very useful, both inside and outside the machine through the source debugger, you can directly use!)
