[mercury-users] uniqueness

[Robert Ernst Johann JESCHOFNIK]

Hello.

I am rather  vague on the uniqueness of types/objects, and how/when to use
uniqueness information...

If I were to represent a matrix of floats as follows:
:- type f_matrix --->
        f_matrix(
                  int, % M
                  int, % N
                  array(float)
                ).

what implications would that have when I deconstruct some object of type
f_matrix to do an array__set, for example? (using destructive update)
Do I actually have to use uniq_array(float) instead? Do those two integers
also have to be unique, to keep the whole f_matrix unique?


thanks..
Rob
