It is Radar System design and signal prcessing code based on standard algorithm .this is vey important for biggener those who are working on Radar signal processing area.This code contain various chapter. this is basically chapter No6

该程序是计算二维wigner分布的复杂函数 Calculates the 2D Wigner distribution of a complex function. (The program is to calculate the distribution of two-dimensional wigner complex function Calculates the 2D Wigner distribution of a complex function.)

数字通信系统QAM仿真程序，基于MATLAB。(QAM digital communication system simulation program, based on MATLAB.)

legendshrink reduces the amount of horizontal space taken up by a figure legend by reducing the length of lines. (Best results when the legend box is off.) This is important for small plots because the size of the lines is constant irrespective of the physical size of the figure. Only works for vertical legends, for now.

采用了精确一维搜索法进行目标函数求极值，其中使用了黄金分割法，最速下降法和拟牛顿法。(Using the exact one-dimensional search method to the objective function extremum, which uses the golden section method, steepest descent and quasi-Newton method.)

先定义蔡氏方程，再利用ode45画出蔡氏方程的分岔图(we give the equation of chua,then use ode45 function to solve and plot the bifurcation diagram.)

matlabWARSHELL算法，用来解决图论问题(WARSHELL ckckckkckkckckkckkck)

此程序为改进后的cma算法，纠正了相位的偏移，对于研究cma算法的有帮助(This program improved cma algorithm to correct the phase offset for cma algorithm)

说明：  基于遗传算法的光学薄膜设计优化MATLABcode(optical thin films design based on GA algorithms )

说明：  s transform of any i-d signal
