Constructor & Destructor Documentation sc::RefSymmSCMatrix::RefSymmSCMatrix () Initializes the matrix pointer to 0. The reference must be initialized be- fore it is used. sc::RefSymmSCMatrix::RefSymmSCMatrix (const RefSCDimension & d, const Ref< SCMatrixKit > &) Create a vector with dimension d by d.
