 a=min(A(:));
 b=max(A(:));
 B=(A-a)/(b-a);

You can use a structure:

p.row = 2;
p.Col = 1;

Or you can use a single number if you use sub2ind to get a linear index

p = sub2ind(matrixSize, row, col);

Chances are that you don't really need to or want to do either of those. Chances are you can just make a logical array but I don't really know how to tell you the best way because I don't have the larger picture/context so all I can do it to tell you exactly what you asked, which like I said is probably not the best approach.
