unconstrained tool, evaluated the objective Hessian in sparse format.
[SH,ICNH,IRNH] = ush(X)
real vector, variables of the problem
real vector, Hessian coefficiants. SH(i) gives the value of the nonzero in row IRNH(i) and column ICNH(i). Only the upper triangular part of the Hessian is stored.
vector of column indices of the nonzeros of the Hessian matrix.
vector of row indices of the nonzeros of the Hessian matrix.
ush evaluates the Hessian matrix of the objective function of the problem decoded into OUTSDIF.d at the point X in the case where the only possible constraints are bound constraints.
