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。

Finds the polynomial p10 of degree less than or equal to 10 that interpolates
cos x on the interval [0, PI/2] at 11 equally spaced points. Study the error betwee
between the function and the polynomial at 41 equally spaced points over the
same interval. Repeat the latter but use your 11 points to be Chebyshevs.
