说明：  matlab数学建模的基础知识讲解，介绍MATLAB在概率统计中的若干命令和使用格式。(A Course of Mathematical Modelling)

用Matlab实现Hash算法下大篇幅文本文件中字符出现的频率的统计！非常精炼！(Hash algorithm used Matlab to achieve great length text file in the frequency character of the statistics! Very refined!)

改程序是在时间序列分析中针对加窗函数来处理和估计密度函数系数(Change process is in time series analysis window function for Canada to deal with and the estimated density function coefficients)

已知观测数据为A+W(n)，其中A为直流信号，W为复高斯噪声，服从CN（0， ），在统计N次下，计算X的统计平均值 ，求T(x)= 的pdf：p(T(x)|H0)、p(T(x)|H1)。 H0： W H1： A+W (Known observation data A+W (n), where A is the DC signal, W is the complex Gaussian noise, subject CN (0,), N times in the statistics, the calculation of the statistical mean of X, find T (x) = a pdf : p (T (x) | H0), p (T (x) | H1). H0: W H1: A+W)

三次样条插值函数，可以直接调用，本人亲测过来，用了matlab现成的函数在里面(Matlab cubic spline interpolation function can be called directly)

求解非线性最化的局部最优解,matlab,matlab例程(Most of solving nonlinear partial optimal solution, matlab, matlab routines)

本程序实现对图像的增强，通过模糊增强算法，使图像的边缘信息更加明显，图像出来，能够更好的处理高频信息(This procedure to achieve an image enhancement, through the fuzzy enhancement algorithm, so that the edge of the image information more clearly, the image out, better able to deal with high-frequency information)

在AR人脸库上进行DCT变换，使用DCT变换后的图像进行 kernel fisher discriminant analysis,其中kernel 函数可以自己选择(In the AR face database on the DCT transform, using the DCT transformed image kernel fisher discriminant analysis, which can choose the kernel function)

说明：  电力系统潮流程序，用matlab编程的的。潮流计算是电力系统运行分析和规划设计中最常用的工具，电力系统潮流计算问题在数学上是求解一组多元非线性方程，迭代的收敛性是实用者关心的技术焦点。(Power Flow procedures, with the matlab programming. Flow calculation is the electric power system operation analysis and planning and designing the most commonly used tools, electric power system power flow calculation problem solving in mathematics is a set of multiple non-linear equations, iterative convergence is a practical technology were the focus of concern.)

微动经典文献，可以帮助大家学习微动方面的知识。里面包含三篇文献，都是雷达目标回波的。(Fretting classic literature can help us learn fretting area. Which contains three documents are radar target echo.)
