This command is used to construct a sparse symmetric system of equations which uses a row-oriented solution method in the solution phase. The following command is used to construct such a system:
| system SparseSYM |
NOTES:
- versions upto and including 2.2.0 use SparseSPD instead of SparseSYM as the option to the system command. For backward compatability this old option continues to work.
