Constructor & Destructor Documentation

sc::RefDiagSCMatrix::RefDiagSCMatrix ()

Initializes the matrix pointer to 0.

The reference must be initialized before it is used.

sc::RefDiagSCMatrix::RefDiagSCMatrix (const RefSCDimension &, const Ref< SCMatrixKit > &)

Create a diagonal matrix with dimension d by d.

The data values are undefined.

Member Function Documentation

RefDiagSCMatrix sc::RefDiagSCMatrix::block (int i) const

If this matrix is blocked return block i.

Otherwise return this as block 0.

int sc::RefDiagSCMatrix::nblock () const

If this matrix is blocked return the number of blocks.

Otherwise return 1.
