摘要
本文用追赶法给出了一类三对角方程组的解的估值，用多种方法证明了一个矩阵的非奇异性，用数值例子比较了线性方程组的迭代算法。
This paper is a teaching note.An estimation of solution for a linear equations having tridiagonal matrix is given by double sweep methods.The nonsingularity of a matrix has been proved by several methods.In order to help understanding iterative method,we supply several examples.
