pathbetweennodes using GPU

[eragonngo]

Hi Kearney,
I wonder if this code work with GPU Array, let's say

SparseGraphGPU=gpuArray(SparseGraph);
MatrixGraphGPU=gpuArray(MatrixGraph);
possible_path = arrayfun( @pathbetweennodes, SparseGraphGPU,1,length(MatrixGraphGPU));

And under your pathbetweennodes, can I use parfor instead of for ?

I think it does not work with parfor because the var visited is shared and updated by each "while" cycle.
What's more, there is no for cycle in this function. The only cycle is while.
