This command is used to construct a sparse symmetric system of equations which uses a row-oriented solution method in the solution phase. To 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. This option continues to work.
