I have four 4x4 matrices that I want to concatinate together to make 1 8x8 that will contain 1's and 0's. How can I check to see if when I combine the 4 together that I do not create areas that are "isolated". In other words sections of 1's that are not connected to the rest of the 1's. Connecitons would be if a 1 has another 1 above, below, to the right or to the left.
I can some challenge with the edges of the matrix and if there are any peninusla type regions.
thank you
Andrew
