Hi All,
I am trying to convert this matrix:
A = [0 1 1 0 1;1 1 1 1 0;1 0 1 1 0]
to:
B = [1 2 2 3 4;2 2 2 2 3;2 5 2 2 3]

The value of matrix A is 0 or 1. I need to make variable clusters for the same values and change the values to the index cluster but don't know how to do it.

Thanks,
GP

Use BWLABEL, first on A then on 1-A. Combine the two results by filling in
the zeros in one of them with the nonzeros (appropriately scaled) from the
other.
