罚函数法将有约束最优化问题转化为求解无约束最优化问题。在此给出罚函数法Matlab源程序(Penalty function method will be constrained optimization problem into solving unconstrained optimization problems. This gives the penalty function method in Matlab source)

该程序输入两个频率值以及一个时间变量，计算时间序列，并对事件序列做出傅里叶分析(Enter the two frequency values ​ ​ of the program and a time variable, calculate the time series, Fourier analysis and the sequence of events to make)

this is the first project which i was done before my conv asqur

这里面有两个程序，两个都是采用4QAM调制。不过个人觉得第一个更容易懂，因为写的很有条理。我改的那个程序就是根据这个来的。 不过在这里面有个问题就是信道系数只能是由高到低，大家可以试试，改成[0.227 0.46 0.688 0.46 0.227]这个是老师给我的仿真中常用的信道系数，这个成为归一化信道，就是系数平方和为1. 第二个程序没有涉及到信道系数，但是这个程序当中，在128个子载波中，前后有32个空载波，这个在OFDM中也是经常用的，这样可以降低误码率。 (And there are two programs, two are based on 4QAM modulation. But personally feel that the first is easier, because the writing is organized. I changed that procedure is based on the past. However, there is a problem in that there is only channel coefficients from high to low, we can try and change into [0.227 0.46 0.688 0.46 0.227] This is the teacher gave me the simulation channel coefficient commonly used, this became normalized channel, is coefficient of the square and is 1. The second program is not related to channel coefficients, but this program which, in the 128 sub-carriers, the before and after the 32 air carriers, the in OFDM is also often used, which can reduce the error rate.)

matlab 关于光学方面的仿真，几何光学，波动光学等函数(simulation matlab optics, geometrical optics, wave optics, and other functions)

曲线拟合实例，可运行，简单明了，一看就懂，供交流探讨。(Curve fitting instance, can run, simple to understand at a glance, for the exchange of.)

matlab程序资料请大家指教，辛苦大家啦(matlab program information, please advise, hard everyone!)

this is mpc example ....

这些主要是讲解数值积分算法的...通过MATLAB编程来实现这些算法(These are mainly on the numerical integration algorithm ... through MATLAB programming to achieve these algorithms)

This project will do encryption by reserving room before encryption for better performance of the compressed image
