NEPComputeFunction

Computes the function matrix T(lambda) that has been set with NEPSetFunction().

Synopsis

#include "slepcnep.h" 
PetscErrorCode NEPComputeFunction(NEP nep,PetscScalar lambda,Mat *A,Mat *B,MatStructure *flg)
Collective on NEP and Mat

Input Parameters

nep - the NEP context
lambda - the scalar argument

Output Parameters

A - Function matrix
B - optional preconditioning matrix
flg - flag indicating matrix structure (see MatStructure enum)

Notes

NEPComputeFunction() is typically used within nonlinear eigensolvers implementations, so most users would not generally call this routine themselves.
