#include "petsctao.h" PetscErrorCode TaoSetOptionsPrefix(Tao tao, const char p[])
Logically Collective on Tao
| tao | - the Tao context | |
| prefix | - the prefix string to prepend to all TAO option requests | 
For example, to distinguish between the runtime options for two different TAO solvers, one could call
      TaoSetOptionsPrefix(tao1,"sys1_")
      TaoSetOptionsPrefix(tao2,"sys2_")
This would enable use of different options for each system, such as
      -sys1_tao_method blmvm -sys1_tao_gtol 1.e-3
      -sys2_tao_method lmvm  -sys2_tao_gtol 1.e-4
