How to create a multidimensional variable in ilog with Java interface?

Question

I want to model a problem with a variable x[i][j][k].

No where in the reference manual is there mention of how to create a variable with size greater than 1 dimension.

Answer 1

This snippet shows an example of creating three indexed continuous variable x, x[i][j][t] in [0,1]:

  IloNumVar[][][] x = new IloNumVar[numNodes][numNodes][numDays];
  for(int i = 0; i < numNodes; i++) 
  {
    for(int j = 0; j < numNodes; j++)
    {
      //cplex is an instance of class IloCplex
      x[i][j] = cplex.numVarArray(numDays, 0, 1); 
    }
  }
