USETUP − CUTEr tool to set up the data structures for unconstrained minimization.

CALL USETUP( INPUT, IOUT, N, X, BL, BU, NMAX )

The USETUP subroutine sets up the correct data structures for subsequent computations in the case where the only possible constraints are bound constraints.

The arguments of USETUP are as follows

INPUT [in] - integer

the unit number for the decoded data; the unit from which OUTSDIF.d is read,

IOUT [in] - integer

the unit number for any error messages,

N [out] - integer

the number of variables for the problem,

X [out] - real/double precision

an array which gives the initial estimate of the solution of the problem,

BL [out] - real/double precision

an array which gives lower bounds on the variables,

BU [out] - real/double precision

an array which gives upper bounds on the variables,

NMAX [in] - integer

the actual declared dimension of X, BL and BU.

A call to USETUP must precede calls to other evaluation tools for unconstrained and bound constrained problems.
