thomas algorithmelementary column operationsTo solve tridiagonal systems of linear equations, the Thomas Algorithm is a much more efficient method than, for instance, Gaussian elimination. The algorithm uses a series of elementary row operations and can solve a system of n equations in O(n) ...
做三次样条曲线时,需要解三对角矩阵(Tridiagonal Matrices)。常用解法为Thomas Algorithm,又叫The tridiagonal matrix algorithm (TDMA)。它是一种基于高斯消元法的算法, 分为两个阶段:向前消元forward elimination和回代backward substitution。本文以一个6乘6矩阵为例,介绍一下使用TDMA的求解过程。 1.范例求解 步骤1...
