Is class IloNumArray2 and IloNumArray3 now default in cplex?

    Hi everyone
     
    I am now learning to use C++ and cplex to do optimization. Have some AMPL experience before.
     
    I am trying to build 3D matrix for my 3D parameters.
    I remember we need to do typedef to define class for 2D or 3D matrix before, like
     
    typedef IloArray<IloNumArray>     IloNumArray2;
    typedef IloArray<IloNumArray2>    IloNumArray3;
     
    But now I find it seems to be no need to do so. It seems IloNumArray2 and IloNumArray3 are already built in cplex now and I can use them directly. Is that correct?

    I found it is very strange that after I sued "typedef IloArray<IloNumArray2> IloNumArray3" and "IloNumArray3 x (env)", I got red underline when I try to do file >> x for data input. The error is "no operator ">>" matches these operands". But if I remove the typedef thing and use IloNumArray3 directly. Its fine. Very strange.

     

    My Visual Studio should be 2010 version, but cplex should be the latest or at least very new.

    Please kindly help to answer if you know. Thanks in advance

    Correct. As you can see in the ilconcert/iloenv.h header file, types IloNumArray2 and IloNumArray3 are types defined by CPLEX. For these types operator>> is also overloaded.

    Hi  Daniel,

                  I am also facing the same problem while building 2D and 3D matrix.

        I have one boolean matrix. I have  defined it :

            typedef IloArray<IloBoolArray> BoolMatrix;

       after that  I declared it:

     BoolMatrix Assigned(env);

    but while trying input data by file >> Assigned, it is showing error (no operator ">>" matches these operands). Whatever suggestions you have already discussed here(removing typedef, and directly put IloBoolArray2 Assigned(env) ) I tried ,but it is not accepting IloBoolArray2. )

     

    Thanks

    Please don't ask the same question in multiple places. And if you ask the same question in multiple places then please at least cross-reference them. You asked the same question here.
