I'm using Gecode 1.2.2 and am wondering if there is a common practice

(From what I see, MiniModel::Matrix is for 2-d matrices).
Can it be done using the available variable array classes? (building
arrays of arrays of IntVarArrays) ?
Hi,
The Matrix class is, as you've correctly identified, a 2-d matrix class.
Before we had the Matrix class, our common practice for matrices was
to declare an IntVarArray and then to write accessor-functions like to
following
IntVar& y(int i, int j) {
return x[i*n*n+j];
}
This idea can be naturally extended to handle more than two dimensions.
Cheers,
Mikael
