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 nonlinear eigensolver 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.
