SVDConvergenceTestFn

A prototype of an SVD convergence test function that would be passed to SVDSetConvergenceTestFunction()

Synopsis

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode(SVDConvergenceTestFn)(SVD svd,PetscReal sigma,PetscReal res,PetscReal *errest,void *ctx);

Calling Sequence

svd  - singular value solver context obtained from SVDCreate()
sigma  - computed singular value
res  - residual norm associated to the singular triplet
errest  - [output] computed error estimate
ctx  - [optional] user-defined context for private data for the convergence test routine (may be NULL)
