BLLS is a solver for bound-constrained linear least-squares problems written in matlab. The method is intended for small-dimensional problems. It is an active-set algorithm where the unconstrained problem is solved at each iteration in the subspace defined by the currently active bounds, themselves being determined by a projected Cauchy step.
