一元五次方程的求解

鉴于算术表达式中的 x 符号，例如，24 （3 + 5） = 5， 写一个程序来读取了一个输入行中给出的表达式，解析它，对其进行计算和 给出了输出值作为单个整数或打印的字符串输入错误"如果输入格式不正确。

两个链表情况下的排序-Sort under two list circumstance

一个程序，实现快速傅立叶变换，使用对话框编程。具体参数可以调节。-a procedure, fast Fourier transform, the use of dialog programming. Specific parameters can be adjusted.

机械原理课程设计,牛头刨床的动力学分析，及动画演示。-mechanical principles to the curriculum design, Shaper of the kinetic analysis, and animation demo.

由于对两次以上的高次函数求解比较不方便 本程序将为你提供便捷-due to more than two high-function solution more inconvenient this program will provide you with convenient

软件开发中很多时候会用到助记符，这个转换源码可以带替手工转换的麻烦。可以根据汉字自动转换，开发者可根据源码灵活运用。这是一个很实用的源码。

void CRandDlg::OnOK()  { // TODO: Add extra validation here int a[7]; int b=0; srand((unsigned)time( NULL ));  for (int i=0;i

概率论与数理统计中的F分布函数，有了它，可以免去查教科书附表的繁琐-probability theory and mathematical statistics of the distribution function F, With it, check the textbook can avoid the cumbersome Schedule

傅立叶变换是信号处理时最常用的算法之一，实现时域与频域之间的转换，对人们研究各种信号非常有用，本程序利用VC实现快速傅立叶变换算法-Fourier transform signal processing is the most commonly used algorithm, achieving time-domain and frequency domain between the conversion of the people look very useful signal, the procedure used VC Fast Fourier Transform algorithm

一、 一元三次回归方程 CubicMultinomialRegress.cs 方程模型为Y=a*X(3)+b*X(2)+c*X(1)+d 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d,c,b,a。 以后所述所有模型的系数存放均与此相同（多元线性回归方程除外）。 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。 -1, one dollar three regression equations CubicMultinomialRegress.cs equation model for Y = a* X (3)+ B* X (2)+ C* X (1)+ Dpublic override double [] buildFormula () get coefficient array, store order and model coefficients contrary, that is, the array is followed by the value of coefficient d, c, b, a. After all the model described in the coefficient of storage are the same (except for multiple linear regression equation). 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 dat
