说明：  多项式相加简单程序，欢迎大家评价~~~~~(Add a simple polynomial procedure, welcome to evaluate ~~~~~)

非线性规划，二次规划SQP，matlab程序求最优值(Nonlinear Programming)

Matlab教程第七章案例，面板数据分析、计量(Matlab Guide Chapter VII of the case, panel data analysis, measurement)

选题二、基于matlab简单图像处理系统用中值滤波方法消除噪声(Two topics, based on matlab image processing system with a simple median filter to eliminate noise)

基于BP神经网络的字符识别算法源代码，包括网络仅值训练方法，训练是通 过调用34个字符文件夹，识别率达到99.8 。(BP neural network-based character recognition algorithm source code, including the value of the network only training methods, training is by calling the 34-character file folders, the recognition rate of 99.8 .)

matlab的gscale函数功能是将强度图像等映射到别的值范围。(Function of matlab gscale intensity images is mapped to another range.)

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)

matlab计算排列熵的程序,可以定量分析混沌或噪声序列的复杂度(a program that is capable of computing the permatation entropy of a time series noise or chaos waveform.)
