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 )

说明：  绝对原创的matlab 量子免疫遗传算法。改程序功能是实现求一个函数的最小值。可运行 (又发一遍，说我格式不对，不知有没有成功)(matalab QGA.)

程序计算了压电铌酸锂薄板中Lamb波传播时的相速度(The program calculates the phase velocity of the piezoelectric thin lithium niobate when the Lamb wave propagation)

The sourcecode of Universally-Convergent Squared-Operator Iteration Methods for fig3 using SOM

VC＋＋环境下调用MATLAB程序实现数字信号处理的方法(VC environment MATLAB program called digital signal processing methods)

可以产生不同调制方式的信号，包括bpsk,qpsk,fsk,msk,16qam,64qam.可以产生不同的样本。(Can generate a signal of different modulation methods, including bpsk, qpsk, fsk, msk, 16qam, 64qam. Can produce different samples.)

跟踪目标的matlab程序，非常有用, 比较实用(Target tracking matlab procedures, very useful)

这是本人原创的关于组合投资问题1数学建模论文，希望对参加数学建模建模的同学有帮助(This is my original portfolio problem of mathematical modeling papers, I hope to help students to participate in the mathematical modeling modeling)

信号的一些时域指标计算，有效值，峰峰值，峭度，能量，倾斜度等(Calculation, effective value, some indexes of time domain signal peak, kurtosis, energy, gradient)
