说明：   模拟退火算法求函数 f(x)的最小值点， 且 l <= x <= u f为待求函数，x0为初值点，l，u分别为搜索区间的上下限，kmax为最大迭代次数 q为退火因子，TolFun为函数容许误差 算法第一步根据输入变量数，将某些量设为缺省值( Simulated annealing algorithm of a function f (x) the minimum point, and l &lt = x &lt = u f is the unknown function, x0 as the initial point, l, u, respectively, lower and upper limits for the search interval, kmax is the maximum q iterations for the annealing factor, TolFun as a function of allowable error algorithm is the first step according to the number of input variables, set default values for certain amount of)

说明：  模糊聚类中的传统闭包法进行模糊等价矩阵的计算，中文解释清晰，可运行，是学习的好案例！(using this program to take fuzzy equilbrium matrix calculation, which is clear for learning fuzzy clustering.)

使用upwind，Lax-Wenfroff以及Crank-Niclson方法实现扩散对流方程数值求解(Upwind, Lax-Wenfroff and the Crank-Niclson method to achieve the diffusion convection equation numerical solution)

真实模拟人走路，通过调节参数可改变人行走的速度，图形化界面操作，含源代码。(To simulate the human walk.)

自适应线谱增强算法通过自适应技术减弱噪声，并增强有用信号的功率谱。(This demonstration illustrates the application of adaptive filters to signal separation using a structure called an adaptive line enhancer (ALE). In adaptive line enhancement, a measured signal x(n) contains two signals, an unknown signal of interest v(n), and a nearly-periodic noise signal eta(n). The goal is to remove the noise signal the measured signal to obtain the signal of interest)

说明：  一个用于求圆周率pi的matlab算法。题目背景：取一长面积为1平方米的正方形白纸，在白纸的内部画一个直径为1米的圆，如下图所示。此圆恰好与正方形的四条边分别切于一点，它的面积是 pi*（1/2）^2 =pi/4 ,然后，你可以抓一大把芝麻，一粒一粒地随便地扔到白纸上。在你扔麦子的过程中可以请一位朋友帮助记录：一共扔了几次？有几次是扔在圆里面？ 实验结束后，你只须用“芝麻落在圆里的次数”除以“一共扔的次数”得到的结果就是圆的面积。则pi就是“圆的面积*4”了 当然，你扔的次数越多，结果就越精确！()
