#include "slepcfn.h" PetscErrorCode FNSetMethod(FN fn,PetscInt meth)Logically Collective on fn
fn | - the math function context | |
meth | - an index identifying the method |
-fn_method <meth> | - Sets the method |
If meth is currently set to 0 (the default) and the input argument A of FNEvaluateFunctionMat() is a symmetric/Hermitian matrix, then the computation is done via the eigendecomposition of A, rather than with the general algorithm.
