Documentation

HCL_UMinHessMethod provides easy access to the UMinHess methods. The choice of method, by name, forms the parameter list. At present the only valid choice is SteihaugToint, a conjugate-gradient based trust region method.

IMPORTANT NOTE: this version (9/97) does not enable specification of various sorts of preconditioning options offered by the UMin constructors. For the moment users wishing to use these features will need to use the UMin constructors directly.

Constructors and destructor
