图形的广度优先搜寻法-graphics breadth priority search method

数值计算方法里的一种经典算法,追赶法,用于大型稀疏方程组-numerical calculation method"s a classic algorithms, catching up with the method for large sparse linear equations

一个比较简单的算法程序。输入一些数，计算后按照矩阵的形式输出。设了三个数组a[]，b[]，c[]。分别实现c[]=a[]+b[]，c[]=a[]-b[]，c[]=a[]*b[]。-a relatively simple procedure of the algorithm. The importation of some few, calculated in accordance with the matrix in the form of output. Established three array a [], [] b, c []. C respectively, to achieve a = [] [] [] b, c = a [] []- [] b, c [] [] = a* b [].
