matlab的教程，有简易版和详细版。较为浅显易懂，对于新手来说，能够较快的入门。(matlab tutorial, there are simple and detailed version version. Relatively easy to understand for the novice is able to fast entry.)

本压缩包包含（1、可编程控制器的编程指令2、运料小车控制模拟3、相鼠笼式异步电动机星/三角换接启动控制4、四节传送带的模拟）(This compressed package contains (1, 2 programmable controller programming instructions, material transport car control simulation 3-phase Squirrel Cage Induction Motor Star/Delta Start Control for 4 then, four belts of simulation))

矩形域上的二阶椭圆差分格式，适合偏微分方程的学习，是有限差分格式(this is the equetion about the partial differetial equotion)

线性矩阵不等式的解法关于matlab(LMI matlab)

实现ID3决策树算法，可以实现基本眜分类，最终的决策树是以结构体存放的(ID3 decision tree)

这个Matlab程序实现最速下降算法。最速下降法是一种最基本的算法，它在最优化方法中占有重要地位.最速下降法的优点是工作量小，存储储变量较少,初始点要求不高；缺点是收敛慢，最速下降法适用于寻优过程的前期迭代或作为间插步骤，当接近极值点时，宜选用别种收敛快的算法. (The Matlab program to achieve the steepest descent algorithm. Steepest descent method is a basic algorithm, it occupies an important position in the optimization method. Advantage of the steepest descent method is the small amount of work, less storage reservoir variables, the initial point less demanding drawback is slow convergence, the steepest descent method for the optimization process of the early iterations, or as inserted steps are advised to use other kinds of fast convergence of the algorithm when close to the extreme point.)

主成分分析的代码，数据处理的必备，方便实用！！(Principal component analysis of the code, the data processing required, convenient and practical! !)

在EFI架構下寫一隻PPI sample(PEIM to PEIM Interface),使兩隻PEIM可透過此PPI互相傳遞資料. Write a PPI sample to make two PEIMs able to communicate each other.(Write a PPI sample to make two PEIMs able to communicate each other.)

关于小波包奇异值的程序，很好用的，而且配上了关于小波包奇异性的相关知识！(The program about the singular value of the wavelet packet is very useful, and it is matched with the related knowledge about the singularity of the wavelet packet.)

相位编码信号的波形的生成，并且其模糊函数的计算，和模糊函数的图形。(Phase coded waveform generation, and its ambiguity function calculation, and the ambiguity function of the graphics.)
