Detailed Description

The SymmSCMatrix class is the abstract base class for symmetric double valued matrices.

Member Function Documentation

◆ assign()

void sc::SymmSCMatrix::assign ( SymmSCMatrix m)
inline

Make this have the same elements as m.

The dimensions must match.

◆ get_subblock()

virtual SCMatrix* sc::SymmSCMatrix::get_subblock ( int  br,
int  er,
int  bc,
int  ec 
)
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.
