3.2.3.4. SuperLU System

This command is used to construct a SparseGEN linear system of equation object. As the name implies, this class is used for sparse matrix systems. The solution of the sparse matrix is carried out using .. SuperLU. To following command is used to construct such a system:

system SuperLU

Note

  1. When using the SuperLU system, the software will renumber the equations to ensure a fast solve. As a consequence it is a waste of time specifying anything but a Plain numberer.

  2. The original and still working command was system SparseGEN

Example

The following example shows how to construct a SuperLU system

  1. Tcl Code

system SuperLU

  1. Python Code

system('SuperLU')
