TaoSetConvergenceTest

 Sets the function that is to be used to test for convergence o fthe iterative minimization solution. The new convergence testing routine will replace TAO's default convergence test.

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoSetConvergenceTest(Tao tao, PetscErrorCode (*conv)(Tao,void*), void *ctx)
Logically Collective on Tao

Input Parameters

tao - the Tao object
conv - the routine to test for convergence
ctx - [optional] context for private data for the convergence routine (may be NULL)

Calling sequence of conv

  PetscErrorCode conv(Tao tao, void *ctx)

tao - the Tao object
ctx - [optional] convergence context

Note: The new convergence testing routine should call TaoSetConvergedReason().
