正交最小二乘辨识算法 该算法除了实现最小二乘辨识功能之外而且能按照各项重要性将其逐一选出并且估计相应系数(OLS Orthogonal Least Quares. [x, ind] = OLS(A,b,r) gives the solution to the least squares problem using only the best r regressors chosen from the ones present in matrix A. This function also returns in the vector ind the indexes of the best r regressors (i.e., the best columns of A to use). If r is equal to n, the solution x given by OLS is the same as the solution given by A, but in ind we still have the regressors sorted by their importance. This means that one can perform a feature selection by taking the first k entries in ind (k<r).)

Matlab 高级编程文档，内容丰富，详细(Matlab high-level programming document, detailed, rich)

说明：  这是基于MATLAB中的stateflow的一个简单的单水箱状态机(Single Water Tank State Machine)

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.

说明：  本套资料,包含了各种Matlab和C++混合编程的例子和理论.是研究Matlab 和VC CBuilder的最权威和经典的例子.在网上搜集的时候发了一个下午的时间。结果发现内容太少了.不得不到我们学校的图书馆去找了。找遍了整个中国期刊全文数据库(CJFD),才找到了这几篇对与编程人员来说的有帮助和参考的文章了。发了我好几块钱了，希望对那些Matlab与Vc和Cbuilder混合编程的人员有很大的帮助了.(the sets of data, including a variety of mixed Matlab and C programming examples and theory. Research VC CBuilder Matlab and the most authoritative and classic examples. The online collection of hair at a time. The results showed very little content. Our school had to find a library. Grateful the entire CJFD (CJFD), they will find this program with a few pairs of officers help and reference of the article. I made a few good money in the hope that those with vitamin C and Matlab Cbuilder mixed programming staff have great help.)

这段程序是用来实现最优控制的，一段是关于倒立摆系统的，还有一个是一本书上的例题。比较适合初学者。(This procedure is used to achieve optimal control, a section is about the inverted pendulum system, there is a example on a book. More suitable for beginners.)
