Matlab编程（Stephen.J.Chapman编.刑树军.郑碧波译.），适用于初学者快速入门。(Matlab programming, suitable for beginners to get started quickly.)

说明：  压缩感知的例子。重建是用在稀疏域上求最小零范数的方法。首先把零范数凸松弛为一范数，然后变成线性规划问题，从而求得最优解。(An example of the compressive sensing. Its reconstruction is based on L0-norm minimization.)

Principal component analysis for dimension reduction

tsp problem, nn algorithm

系统的介绍了matlab的用处，新手很容易看懂。(The book is a very good book of the introduction of matlab.)

用有限元方法解偏微分方程的算例。区域是[0,1]*[0,1]的正方形区域，区域剖分网格是标准正方形。区域剖分、节点计算、转化成代数方程求解，结果画图显示及txt结果输出，每一步都很详细。(Two-dimensional numerical example of using the finite element method for solving partial differential equations . Region is a [0,1]* [0,1] of the square region, a square region of a standard mesh grid. Regional split, node calculation, converted into algebraic equations, the results display and txt file result output, each step is very detailed.)

这是一个债券交易策略。由2条交叉线产生交易信号。( This MATLAB function implements a simple band trading strategy. A band consists of two lines that form the upper and lower boundaries of the band. The upper and lower boundaries are used to to enter and exit trades. For example, if prices fall below the lower boundary a buy signal is generated. )
