Lets say the array is like this:
A = [4 4 4 4 6 6 6 6 6 6 2 2 3 3 3 5 5 5 5 5 3 3 3];
How could I change the matrix to be like this:
B = [4 0 0 0 6 0 0 0 0 0 2 0 3 0 0 5 0 0 0 0 3 0 0];
I want to represent each new number in the array but not more than once. The numbers may occure several times as number three in this example.
