General Matrix Information

•

model.sol(<tag>).feature(<ftag>).isReal(<mname>) returns true if the matrix <mname> is real.

•

model.sol(<tag>).feature(<ftag>).getM(<mname>) returns number of rows in the matrix <mname>.

•

model.sol(<tag>).feature(<ftag>).getN(<mname>) returns number of columns in the matrix <mname>.

•

model.sol(<tag>).feature(<ftag>).getNnz(<mname>) returns number of nonzero entries in the matrix <mname>.
