Detailed Description
The SymmSCMatrix class is the abstract base class for symmetric double valued matrices.
Member Function Documentation
◆ assign()
|
inline |
Make this have the same elements as m.
The dimensions must match.
◆ get_subblock()
|
pure virtual |
Return a subblock of this.
The subblock is defined as the rows starting at br and ending at er, and the columns beginning at bc and ending at ec.
Implemented in sc::BlockedSymmSCMatrix, sc::ReplSymmSCMatrix, sc::DistSymmSCMatrix, and sc::LocalSymmSCMatrix.
