实现了对文档的数据读入，实现了文档的数据读入(The realization of the document data read into, The realization of the document data read into, )

说明：  龙格-库塔方法的使用，例子 求y’=y-2x/y，y(0)=0。 解：输入X0=0，X1=1，H=0.2，N=6。()

分别对beta估计值模拟分析、非中心对称分布、卡方拟合优度检验、筛选抽样随机数抽取、有限样本性质模拟这5个内容进行了编程说明(The five contents of beta estimation simulation analysis, non-centrosymmetric distribution, chi-square goodness-of-fit test, random number extraction of screening sampling and Simulation of finite sample properties are explained by programming.)

该程序计算薄板振动固有频率，模态，以及受迫振动时域响应(The program calculates the natural frequencies, modes, and time-domain responses of the forced vibration of the thin plate)

说明：  二维笛卡尔坐标系下网格的划分，包括多重网格等。(Two-dimensional Cartesian coordinate system, the division of the grid, including the multi-grid and so on.)

应用MATLAB编写的偏最小二乘法程序,且具有画图功能(MATLAB prepared by partial least squares procedure, which is drawing functions)

DFP法求优化问题的C++源代码，经测试，该程序运行正常，得到了预期的结果。(DFP method for the optimization of C++ source code, tested, the program works correctly to get the desired results.)

分数傅里叶变换和分数余弦变换，动态展示实部，虚部和模值(Computation of the Fractional Fourier Transform)

一个计算两个信号频率差的Matlab程序,主要用于求多普勒频偏。(A Matlab program to calculate the Doppler shift )

说明：  线性判别分析（LDA，全称Fisher Linear Discriminant Analysis）算法的C#实现源码，根据stprtool box for matlab中的LDA.m编写。用到MathNet库做相关的矩阵运算，使用zedgraph控制绘图。有简单的测试数据。( C# source code of linear discriminant analysis (LDA, full name of the Fisher Linear Discriminant Analysis) algorithm , according to LDA.m of stprtool box for matlab . Use MathNet library to do matrix operations,and use zedgraph control for drawing. Thers has a simple test data.)
