hi, did anybody use the function IloSum. if I want to do such an operation:
for(j=0;j<T;j++)
{c[i][k]+=a[i][j][k]*b[j][k];}
where:
a is IloNumVarArray;
b is constant Array in C++;
can I use IloSum to do this operator???
If it's possible, how to use it??? and what's type should c][ be ????

No, you cannot. IloSum is designed to sum up the elements of a single array. It is shorthand for something like this:

type_t result = 0;
for (i = 0; i < array.size(); ++i)
   result += array[i];
