2004China Undergraduate Mathematical Contest in Modeling (CUMCM)是2004年全国数学建模大赛的题目（B题）。现将题目，建模过程及利用“多元线性回归和人工神经网络”解题的源代码上传给大家一起分享。(2004China Undergraduate Mathematical Contest in Modeling (CUMCM) 2004 National Mathematical Modeling Contest of Title (B items). The topic, modeling process and the use of )

这是基于matlab的电路仿真,程序是自己改写的,还不多,希望大家多多交流.(This is based on Matlab circuit simulation, the process is write, and do not, We hope to conduct more exchanges.)

基于pls对光谱分析 包括数据读取，小波变换PCA分析，PLS建模，交叉验证(Pls include data on the spectrum based on reads, wavelet transform PCA analysis, PLS modeling, cross-validation)

说明：  《数字图像处理与机器视觉:Visual C++与Matlab实现》1 图像的点运算,图像的几何变换,空间域图像增强(&quot Digital image processing and machine vision: Visual C++ and Matlab to achieve&quot an image of the point operation, image geometric transformation, spatial domain image enhancement)

Calculated Powers in 3 Phase

This is consist of converting the matlab code to dll using C++ code

卷积码convolutional codes生成程序，可以方便地生成任意参数的卷积码。(Convolutional code generator.)

基于MATLAB的数字滤波器设计 MATLAB的基本知识 (Digital filter design based on MATLAB' s basic knowledge of MATLAB)

说明：  计算一个方柱的散射的波形，并求其RCS。方柱的网格总数是N=500个，时间步为1200步。网格尺寸为lamda/18,时间间隔是ddx/2*c，c为光速。脉冲源位于中心。方柱边长为7*lamda。并与相同尺度的球的散射场进行对比(Calculate the scattered waveform of a square column and find its RCS. The total number of grids of the square column is N=500 and the time step is 1200 steps. The grid size is lamda/18, the time interval is ddx/2*c, and c is the speed of light. The pulse source is at the center. The side of the square column is 7*lamda. And compare the scattering field of the ball of the same scale)

说明：  用matlab实现clockr仿真，初学试用的小程序(Clock of matlab simulation, a small trial program beginner)
