加窗傅立叶变换及其逆变换的重构，并有详细的注释和例子(Windowed Fourier transform and its inverse transform of the reconstruction, and detailed notes and examples)

该方法给出了一个CG算法求对称正定矩阵的线性方程的解，要求给出矩阵A、向量b和一个探测向量x0。(This method gives a CG algorithm for linear equations of symmetric positive definite matrix, requiring to give a matrix A, a vector b and a probe vector x0.)

本实验要求在学生掌握模糊控制器基本工作原理和设计方法基础上，熟悉MALAB中的模糊控制工具箱，能针对实际问题设计模糊控制器，建立模糊控制系统，训练学生综合运用计算机来解决一些实际问题的能力。(This experiment requires students to master the basic working principle of the fuzzy controller design method based on MALAB familiar toolbox of fuzzy control to practical problems for the design of fuzzy controllers, fuzzy control systems, integrated use of computers to train students to solve some practical problems.)

using L in profile storage. We may solve Ly  b accessing L by row and either LTx  y accesing LT by column or equivalently xTL  yT accessing L by row

随记减量法是从结构的随机振动响应信号中提取该结构自由衰减振动信号的一种方法-With the mind Reduction Act(Reduction Act is credited with random vibration response of the structure from the signal to extract the structure of a method-With free decay vibration signals the mind Reduction Act)

一个matlab的跟踪小例子，功能很简单，容易理解(A small example of the tracking matlab for beginners to use, very simple)
