SVDSetConvergenceTestFunction

Sets a function to compute the error estimate used in the convergence test.

#include "slepcsvd.h" 
PetscErrorCode SVDSetConvergenceTestFunction(SVD svd,SVDConvergenceTestFn *conv,void* ctx,PetscErrorCode (*destroy)(void*))

Logically Collective

	svd	- singular value solver context obtained from SVDCreate()
	conv	- the convergence test function, see SVDConvergenceTestFn for the calling sequence
	ctx	- context for private data for the convergence routine (may be NULL)
	destroy	- a routine for destroying the context (may be NULL)

If the error estimate returned by the convergence test function is less than the tolerance, then the singular value is accepted as converged.
