PURPOSE ^

MPT_MPLP Explicitly solves the given linear program (LP)

SYNOPSIS ^

function [Pn,Fi,Gi,activeConstraints, Phard,details]=mpt_mplp_ver7(Matrices,Options)

DESCRIPTION ^

MPT_MPLP Explicitly solves the given linear program (LP)

 [Pn,Fi,Gi,activeConstraints,Phard,details]=mpt_mplp(Matrices,Options)

 ---------------------------------------------------------------------------
 DESCRIPTION
 ---------------------------------------------------------------------------
 Multiparametric linear programming

 Solves the problem
   V(x) = min (H + Dx)' U
           U
   s.t.   G U <= W + E x
          bndA*x <= bndb

 As a solution we get 'nR' regions
   Pn(i)={x : H x <= K}
 
 with the optimal control law
   U = Fi{i} x + Gi{i}

 and the corresponding cost function expression
   V(x) = Bi{i} x + Ci{i}
  
 ---------------------------------------------------------------------------
 INPUT
 ---------------------------------------------------------------------------
 Matrices - a struct with all the parameters which are needed.
            See description above for explanation.
   Matrices.H=H;
   Matrices.G=G;   
   Matrices.W=W;
   Matrices.E=E;
   Matrices.D=D;    
   Matrices.bndA=bndA;     Limits on exploration space, i.e. bndA*x<=bndb
   Matrices.bndb
   Matrices.constraintInfo;    

 Options.verbose      - level of verbosity
 Options.lpsolver     - which LP solver to use (help mpt_solveLP)
 Options.max_iter     - maximum number of iterations of the algorithm
 Options.step_size    - length of step over a facet (default: 1e-?)
 Options.f_perturb    - Perturbation of the optimization direction

 Note: If Options is missing or some of the fields are not defined, the default
       values from mptOptions will be used

                                 parition indexed by the border numbers
