基于MATLAB的16QAM仿真设计，里面包括若干个M文件，使用者只要在MATLAB环境下运行，就能看到仿真结果。(MATLAB simulation of 16QAM based on the design, which includes a number of M documents, users simply run under MATLAB environment, you can see the simulation results.)

田纳西伊斯曼过程的matlab仿真模块 直接操作即可产生数据 希望对初学者能有帮助 并且可以找到对应的经典文献(Tennessee Eastman process of matlab simulation module direct operation can produce data hope to help beginners can and you can find the corresponding classical literature )

This is a simple function which caculates the spherical harmonic.The archive includes four M files ,and the file Comx_Sph.m is the main function.Given the degree l ,the index m and the variable x ,you can get the value of spherical harmonic.For more details ,you may read the programs.

数字信号处理中的频谱泄露的程序，有助于帮助理解信号滤波处理的内涵。(Digital signal processing procedures spectral leakage, signal filtering helps to help understand the meaning.)

模拟退火算法来源于固体退火原理，将固体加温至充分高，再让其徐徐冷却，加温时，固体内部粒子随温升变为无序状，内能增大，而徐徐冷却时粒子渐趋有序，在每个温度都达到平衡态，最后在常温时达到基态，内能减为最小。 (Simulated annealing algorithm derived from solid annealing principle, the solid is heated to a sufficiently high, let it cool slowly, when heated, solid particles with temperature becomes disordered state, the internal energy increases, while slowly cooling the particles gradually increasingly ordered at each temperature to reach equilibrium, and finally reach the ground state at normal temperature, which can be reduced to a minimum.)

波动方程正演模拟，交错网格二阶和四阶，和规则网格。适合新手学习。(Wave equation forward modeling, suitable for beginners to learn.)

基于Hilbert_Huang变换的基音周期提取方法(basic-speech drawing based on Hilbert_Huang)

Matlab7.x图像处理 光盘内容，吐血推荐，是用MATLAB进行处理的入门书籍之一(CD-ROM content Matlab7.x image processing, hematemesis recommendation is to use MATLAB to deal with one of the entry-book)

非线性光学材料的光限幅特性理论拟合，给出透过光强随输入光强的变化(optical limitting)

MATLAB提供了各种曲线拟合方法，例如：Exponential, Fourier, Gaussing, Interpolant, Polynomial, Power, Rational, Smoothing Spline, Sum of Functions, Weibull等，当然，也可以使用 Custom Equations. cftool不仅可以绘制拟合后的曲线、给出拟合参数，还能给出拟合好坏的评价参数(Goodness of fit)如SSE, R-square, RMSE等数据，非常好用。但是如果我们已经确定了拟合的方法，只需要对数据进行计算，那么这种GUI的操作方式就不太适合了，比如在m文件中就不方便直接调用cftool。 (matlab has given a lot of method for curve combine ,we will give a new method and provide a matlab code.)
