就好比这个图里面点1到点5的最短路径数量就是2个，即点1到点3到点5，点1到点4到点5。这些点和连接都用矩阵来表示，然后通过矩阵来求点与点之间最短路径的数量。这个图的矩阵就是：[0 1 1 1 0; 1...

if you cann't simplify your algorithm and the data accuracy are not the most important,
you can try to use the single data type to reduce your required memory at 50%.
Additional, the Matlab x64 is not limited at 3G Memory, you can take this version for your problem,
good luck
