按列存储三对角矩阵。三对角矩阵可以按行、按列等多种方式存储，本代码是三对角矩阵按列存储的数据结构问题。解决数据结构里面基本的问题，是很好的源代码。

资源描述Write a program to find the weighted shortest distances from any vertex to a given source vertex in a digraph. If there is more than one minimum path from v to w, a path with the fewest number of edges is chosen. It is guaranteed that all the weights are positive and such a path is unique for any vertex.
