googling "floyd algorithm " gave me the folowing

maybe you can modify the above to suit your needs

hi,

floyd on adjacent matrix W for the graph
floyd(W)
{
n is the number of rows in W;
D(0)=W;
for k = 1 to n
for i = 1 to n
for j = 1 to n
{
D(k)[i][j]=MIN(D(k-1)[i][j], D(k-1)[i][k] + D(k-1)[k][j]);
}
}

means for all i and j, I want to know the minimum path between i and j that k participate in the path,
so for all k, i replace D[i][j] with the min of D[i][j] and D[i][k]+D[k][j], that means, if the path between i -> k, and then k ->j is smaller than the path i->j  that doesn't use k in the path, i use this minimum.

note that you can use one D matrix for above operation.

have a good programming day.
