I=j or i!=j

    Sorry, pretty basic, but for the life of me I can't think of the operator... if i=j it would return 1, and if i != j it would return 0...

    no, I remember seeing in a math or physics book once, a mathematical operation that could be done, I believe it was used in context with a summation operator, to obtain a value of 1 if i and j were the same value, and 0 if not.
