PCShellSetApplyTranspose

Sets routine to use as preconditioner transpose.

#include "petscpc.h" 
PetscErrorCode  PCShellSetApplyTranspose(PC pc,PetscErrorCode (*applytranspose)(PC,Vec,Vec))

Logically Collective on PC

	pc	- the preconditioner context
	apply	- the application-provided preconditioning transpose routine

   PetscErrorCode applytranspose (PC pc,Vec xin,Vec xout)

	pc	- the preconditioner, get the application context with PCShellGetContext()
	xin	- input vector
	xout	- output vector

Notes: the function MUST return an error code of 0 on success and nonzero on failure.

Uses the same context variable as PCShellSetApply().
