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)
Collective
Input Parameters#
nep - the NEP context
lambda - the scalar argument
Output Parameters#
A - Function matrix
B - optional preconditioning matrix
Notes#
NEPComputeFunction() is typically used within nonlinear eigensolvers implementations, so most users would not generally call this routine themselves.
