unconstrainted tool, obtain statistics concerning fouction calls.
[time,calls] = ureprt()
a real 2 dimensionnal row vector:
time( 1 ): cpu time (in seconds) for usetup
time( 2 ): cpu time ( in seconds) since the end of usetup
a real 4-dimensionnal row vector:
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
ureprt obtains statistics concerning function evaluation and CPU time used for unconstrained or bound-constrained optimization.
