ush

unconstrained tool, evaluated the objective Hessian in sparse format.

Calling Sequence

[SH,ICNH,IRNH] = ush(X)

Parameters

X

real vector, variables of the problem

SH

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.

ICNH

vector of column indices of the nonzeros of the Hessian matrix.

IRNH

vector of row indices of the nonzeros of the Hessian matrix.

Description

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.
