Scilab Function

udimsh - unconstrained tool, gets the number of non zeros in the Hessian

Calling Sequence

NNZH = udimsh()

Parameters

Description

udimsh gets the number of nonzeros required to store the Hessian matrix of the objective function of the problem decoded into OUTSDIF.d at hte point X in the case where only possible constraints are bound constraints. This Hessian matrix is stored as a sparse matrix.
