SVDStoppingTestFn#
A prototype of an SVD stopping test function that would be passed to SVDSetStoppingTestFunction()
Synopsis#
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode SVDStoppingTestFn(SVD svd,PetscInt its,PetscInt max_it,PetscInt nconv,PetscInt nsv,SVDConvergedReason *reason,void *ctx);
Calling Sequence#
svd - singular value solver context obtained from SVDCreate()
its - current number of iterations
max_it - maximum number of iterations
nconv - number of currently converged singular triplets
nsv - number of requested singular triplets
reason - [output] result of the stopping test
ctx - [optional] user-defined context for private data for the stopping test routine (may be NULL)
