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。

通过C语言编程实现数值计算方法中的雅可比迭代，输入各个方程组的系数和迭代次数可以得到方程的精确解和中间计算结果。另外方程组未知数的个数可以自行设定。-Through the C language programming to achieve numerical method of Jacobi iteration, enter all equations of the coefficients and number of iterations can be exact solutions of equations and intermediate results. Another unknown number of equations can be set.

重言式的判别
资源描述
先来明确一下概念：一个逻辑表达式如果对于其变元的任一种取值均为真，则成为重言式；反之，如果对于其变元的任一种取值都为假，则称为矛盾式，然而，更多的情况下，既非重言式，也非矛盾式。 对于一个逻辑表达式，到底属于上面三种情况的哪一种，可以有很多种判断方法，如真值表法，直接证明法等等，这些你可以参考 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
