Scilab Function udimsh - unconstrained tool, gets the number of non zeros in the Hessian
Calling Sequence
- NNZH = udimsh()
Parameters
- NNZH
: number of nonzeros
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.
