NEPComputeJacobian

Computes the Jacobian matrix T'(lambda) that has been set with NEPSetJacobian().

Synopsis

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

Input Parameters

nep - the NEP context
lambda - the scalar argument

Output Parameters

A - Jacobian matrix
flg - flag indicating matrix structure (see MatStructure enum)

Notes

Most users should not need to explicitly call this routine, as it is used internally within the nonlinear eigensolvers.
