TSPseudoSetTimeStep

Sets the user-defined routine to be called at each pseudo-timestep to update the timestep.

#include "petscts.h"   
PetscErrorCode  TSPseudoSetTimeStep(TS ts,PetscErrorCode (*dt)(TS,PetscReal*,void*),void* ctx)

Logically Collective on TS

	ts	- timestep context
	dt	- function to compute timestep
	ctx	- [optional] user-defined context for private data required by the function (may be PETSC_NULL)

func (TS ts,PetscReal *newdt,void *ctx); -

newdt -the newly computed timestep

ctx -[optional] timestep context

The routine set here will be called by TSPseudoComputeTimeStep() during the timestepping process.
