Hi, Does anyone have a short example of a matrix minimization problem with non-negativity inequality constraints on the variables, solved without turning to Mathematicas NMinimize or Minimize? Preferably in matrix notation. I am able to solve the problem with equality constraints, however the inequality constraint somehow always ends up with 0 as the solution for my variables. I suppose this is solved by Kuhn-Tucker conditions, but I am not able get a solution in Mathematica. Geir Sivertsen
