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.
