ureprt

unconstrainted tool, obtain statistics concerning fouction calls.

Calling Sequence

[time,calls] = ureprt()

Parameters

time

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

calls

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

Description

ureprt obtains statistics concerning function evaluation and CPU time used for unconstrained or bound-constrained optimization.

Examples

sifdecode(get_sif_path()+'sif/AKIVA.SIF',TMPDIR+'/AKIVA')
buildprob(TMPDIR+'/AKIVA')
[X,BL,BU]=usetup(TMPDIR+'/AKIVA/OUTSDIF.d');
[f,g]=uofg(X);
[time,calls] = ureprt()
