Sparse linear algebra » Reference » Support modules » SuperLUSupport module module

Contents

This module provides an interface to the SuperLU library. It provides the following factorization class:

  • class SuperLU: a supernodal sequential LU factorization.
  • class SuperILU: a supernodal sequential incomplete LU factorization (to be used as a preconditioner for iterative methods).
#include <Eigen/SuperLUSupport>

In order to use this module, the superlu headers must be accessible from the include paths, and your binary must be linked to the superlu library and its dependencies. The dependencies depend on how superlu has been compiled. For a cmake based project, you can use our FindSuperLU.cmake module to help you in this task.

Classes
