matlab code to draw the chrometic component of finger

说明：  function [ret,x0,str,ts,xts]=smg(t,x,u,flag) smg is the M-file description of the SIMULINK system named smg. The block-diagram can be displayed by typing: smg. SYS=smg(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

matlab 包括遗传算法等，包括交叉，变异等，包括计算的结果等。 (Matlab bao kuo yi chuan suan fa deng bao kuo jiao cha bianyi deng bao kuo ji suan de jie guo deng)

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.)

The progress of the research in wireless communications and in other areas stimulates the rapid development of WSN. The motivation for the development of WSN is their flexibility, relative ease of installation (e.g., in places with radioactive pollution), lower power consumption etc. As can be concluded from [2], a WSN - is an infrastructure comprised of sensing, computing, and wireless communication elements that provides the ability to instrument, observe, and react to events and phenomena in a certain environment. The information obtained by sensors can be used for civil, governmental, commercial, or industrial purposes.

基于matlab的数字图像的二维傅立叶变换(FFT)以及二维离散余弦DCT变换，提供里详细代码，.m文件(Matlab-based digital image two-dimensional Fourier transform (FFT) and two-dimensional discrete cosine transform DCT offers in detailed code,. M file)

方形晶格的二维光子晶体材料带隙的平面波法模(Two-dimensional square lattice photonic crystal band gap materials, the plane wave method mode)

Matlab语言在天线设计中的使用 很有用的资料(Matlab language design in the use of antenna very useful information)

说明：  基于R/T系数法求解计算瑞利波波速，算法被改进过的，速度很快(Based on R/T coefficient method calculation of the Rayleigh wave speed, the algorithm had been improved, very fast)

本程序可以较好的实现模糊PID控制的功能，给大家提供一种参考。(it s good for fuzzy-PID controler system.)
