eps | - eigensolver context obtained from EPSCreate() | |
func | - a pointer to the convergence test function | |
ctx | - context for private data for the convergence routine (may be null) | |
destroy | - a routine for destroying the context (may be null) |
PetscErrorCode func(EPS eps,PetscScalar eigr,PetscScalar eigi,PetscReal res,PetscReal *errest,void *ctx)
eps | - eigensolver context obtained from EPSCreate() | |
eigr | - real part of the eigenvalue | |
eigi | - imaginary part of the eigenvalue | |
res | - residual norm associated to the eigenpair | |
errest | - (output) computed error estimate | |
ctx | - optional context, as set by EPSSetConvergenceTestFunction() |
