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)

Collective

Input Parameters#

  • nep - the nonlinear eigensolver context

  • lambda - the scalar argument

Output Parameter#

  • A - Jacobian matrix

Notes#

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