SymScaledMatrix Class Reference
#include <IpSymScaledMatrix.hpp>
Detailed Description
Class for a Matrix in conjunction with its scaling factors for row and column scaling.Operations on the matrix are performed using the scaled matrix. You can pull out the pointer to the unscaled matrix for unscaled calculations.
