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 - the singular value solver context

  • 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)
