polynomial spline function

基本解释

The favorate spline function is polynomial in a segment of the domain.
样条函数采用分段的多项式。
The purpose is to estimate unknown parameters and nonparametric function using a polynomial spline method.
旨在利用多项式样条方法，对未知参数和非参数函数进行估计。
A class parametric basis function of the cubic B spline curve are talked about, these parametric basis function are polynomial blending functions of degree , the range of the parameter is given.
讨论了三次B样条曲线的双参数型基函数，这种基函数是四次多项式调配函数，给出了调配函数的参数的取值范围。
