    Hi all,

    I am using cplex with matlab and I couldn't understand

    cplex.Solution.dual
    cplex.Solution.ax
    cplex.Solution.reducedcost

    commands. Especially dual command does not find the dual variable values. But what do they find?:)

    Thanks a lot for helping me regarding this manner.

    ax representing the product of the optimal value of variables and the constraint matrix.
    reducedcost Reduced costs for a linear or quadratic problem.
    dual Dual values for a range of the constraints of a linear or quadratic program.
