Maple目前应用非常广泛符号计算软件之一它拥有非常强大符号计算和数值计算功本书详细地介绍了Maple基本功包括数值计算解方程微积分计算向量及矩阵计算解常微分方程和偏微分方程等本书深入讲解了Maple编程基本原理 -Maple is widely used at present one of the symbolic computation software, It has a very powerful symbolic computation and numerical calculation of power of this book describes in detail the basics of Maple, including numerical solution of equations of calculus, vector and matrix calculations calculation solution of ordinary differential equations and partial differential equations, etc., where Shu-depth briefing on the basic principles of programming in Maple

这里有不少搞过ACM程序设计大赛的达人吧，这篇文章是从网上偶然得到，指出了ACM竞赛赛题的某些发展方向。挺值得一看。-Here has been engaged in a number of ACM programming contest it Tatsu people, this article was obtained from the Internet by accident, pointing out that the ACM contest the title match certain direction of development. Quite worth a visit.

对数回归方程 LogarithmRegress.cs 方程模型为 Y=a*LnX+b public override double[] buildFormula() 得到系数数组，存放顺序与模型系数相反，即该数组中系数的值依次是b,a。 public override double forecast(double x) 预测函数，根据模型得到预测结果。 public override double computeR2() 计算相关系数（决定系数），系数越接近1，数据越满足该模型。 -Logarithmic regression equation LogarithmRegress.cs equation model for Y = a* LnX+ Bpublic override double [] buildFormula () get coefficient array, the storage order and model coefficients contrary, that is, the array is followed by the value of coefficient b, a. public override double forecast (double x) prediction function, according to the results of model prediction. public override double computeR2 () calculated the correlation coefficient (determination coefficient), coefficient of the closer one, the data satisfy the model more.

你好！注意，平均队列长度的理论回答是到达顾客在本系统中的H /（1–H），H是一个客户的平均服务时间，“a”是连续的客户的到达之间的平均时间。乐趣与此代码！！！

串口C程序 ， STC mcu ，循环缓冲区， 解决串口丢数据问题， 实际工程中很稳定， 接收时， 在中断中接收， 写入循环缓冲区， 主程序去循环缓冲区中取数据。
