Fminsearch不承认的约束限制。 不过简单的转换方法存在 转换成一个绑定的约束问题 无约束问题。 Fminsearchbnd用于酷似fminsearch， 除了边界应用到变量。 应用于国内的界限，利用 改造中的变量。 （二次型 单式，双罪恶界（十）。） 具有包容性的不平等的界限，它承认 边界值本身，但不准 在所有函数之外的范围评估。 请注意，fminsearchbnd允许用户准确地固定在某个给定值通过设置一个变量的确切范围相同的值。(Fminsearch does not admit bound constraints. However simple transformation methods exist to convert a bound constrained problem into an unconstrained problem. Fminsearchbnd is used exactly like fminsearch, except that bounds are applied to the variables. The bounds are applied internally, using a transformation of the variables. (Quadratic for single bounds, sin(x) for dual bounds.) The bounds are inclusive inequalities, which admit the boundary values themselves, but will not permit ANY function evaluations outside the bounds. Note that fminsearchbnd allows the user to exactly fix a variable at some given value, by setting both bounds to the exact same value.)

刘老师的变结构控制，修改了符号函数，解决了抖振问题。( Variable Structure Control , modify the symbolic function to solve the chattering problem.)

用于读取mit心电数据库程序，运行环境matlab，对研究心电非常有用！(Mit to read ECG database program, runtime environment matlab, the study ECG is very useful!)

BP网络的MATLAB工具箱的实现。。 ——Bpnet(BP network MATLAB toolbox implementation. .- Bpnet)

该文件是学习matlab的经典教材，国内无法找到，本人从国外所得。(this book is the classical textbook for matlab.it is easy to learn and grasp by matlab engineers.)

说明：  用harris 算子提取特征点 然后求取两帧图像之间的运动参数(Operator Feature Extraction then strike two images among the parameters of the movement)
