Problem 1, Homework 2

For the two functions, the definition of Problem 1 asks you
to allocate space for  pointer C within the definition/implementation
of the function. DISREGARD THIS requirement.

Assume that space has already been allocated i.e. one has already done
something such as C = (FTYPE *) malloc(n*n*sizeof(FTYPE));
But that's all you can assume; initialization  of C is/might still be 
your job.

Thanks to Jonathan K. for pointing out this inconsistency.
