Dear All,

In my algorithm, i need to solve several programs, sequentially. One of them requires constraint matrix A (in Ax=b) as parameter. I don't know how to get that matrix. Is there any way to construct and use the matrix A?

Thanks in advance.

Hi,

normally you don't express you problem as matrix in OPL.

OPL is a way to build this matrix using equations.

But if you want to get the basis of your problem you can use OPL script and get the basis of your problem:

you could also loo at all tyhe methode available at your problem in CPLEX, such getAX()

Hi,

Thank you for answer but I couldn't understand whether the basis provides us to coefficient matrix or not?

Thanks.
