PetscErrorCode NEPSetFunction(NEP nep,Mat A,Mat B,NEPFunctionFn *fun,void *ctx)
Collective
Input Parameters#
nep - the NEP context
A - Function matrix
B - preconditioner matrix (usually same as A)
fun - Function evaluation routine (if NULL then NEP retains any previously set value), see NEPFunctionFn for the calling sequence
ctx - [optional] user-defined context for private data for the Function evaluation routine (may be NULL) (if NULL then NEP retains any previously set value)
