Input Parameters

nep - the NEP context
A - Function matrix
B - preconditioner matrix (usually same as the Function)
fun - Function evaluation routine (if NULL then NEP retains any previously set value)
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)
