UREPRT − CUTEr tool to obtain statistics concerning function evaluation and CPU time used.

CALL UREPRT( CALLS, TIME )

The UREPRT subroutine obtains statistics concerning function evaluation and CPU time used for unconstrained or bound-constrained optimization in a standardized format.

The arguments of UREPRT are as follows

CALLS [out] - real array of length 4

gives the number of calls to the problem functions:

CALLS( 1 ): number of calls to the objective function

CALLS( 2 ): number of calls to the objective gradient

CALLS( 3 ): number of calls to the objective Hessian

CALLS( 4 ): number of Hessian times vector products

TIME [out] - real array of length 2:

TIME( 1 ): CPU time (in seconds) for USETUP

TIME( 2 ): CPU time (in seconds) since the end of USETUP.
