How to determine the number of connected path in percolation modelling

Hi,

I have previously found one percolation example that uses random number generation to create a matrix consisting of '1' or '0'. After that, the program determines if there is continuous '1' throughout the horizontal and vertical direction. I wish to account for diagonal path as well. How can I do this? Thanks a lot.
