Extract coefficients matrix from constraint matrix

[Cheng Wang]

Hi everyone:

    If I have formed the constraint matrix of a optimization problem using yalmip, donated as F. How can I extract the coefficients matrix of F?

    for example, the constraints are as follows

----------------------------------------

         s.t. x1+x2<=1

               x2+x3<=1

              x1+x2+x3<=1

---------------------------------------

   suppose I have promgramed those constraints using yalmip, donated as F. if I want to get the following matrix, is there an existing order?

coefficients matrix of F=[1 1 0; 0 1 1; 1 1 1].

Thanks!

Export to, e.g., quadprog

Thanks!

[model,recoverymodel] = export(F,f,sdpsettings('solver','cplex')) can solve my problem.
