摘要
对由单边基表示的自然样条插值函数提出一种新的构造方法,所得的线性方程组的系数矩阵对称且主对角线元素大部分非零,具有节省存储、计算稳定等优点。
A new construction of interpolation natural splines is developed, in which the matrix of coefficents is symmetric and the main diagonal elements of the mat-rix are mostly non-zero. This method has advantages of saving storageg and main-taining stability in computation.
