   三、在多項式樣條空間、代數(shù)三角樣條空間和代數(shù)雙曲樣條空間這三個具體的ect空間上,給出了相應(yīng)典范ect組和廣義p lya多項式的計算和顯示表示,展示了幾個低階ectb樣條曲線各種插入節(jié)點算法的求解全過程
2. Secondly , we introduce the recurrence definition of the non - uniform algebraic - hyperbolic b - spline basis using divided differences and the de boor - fix recurrence definition on polynomial functions , and based on the new forms , algebraic - hyperbolic b - spline curves are obtained . they share most of the properties as those of the b - spline curves in the polynomial space . we focus on deducing the calculating and knot inserting formulae for this new kind of curves and then prove that they have the variation diminishing properties
