Detailed Description

The RefSCMatrix class is a smart pointer to an SCMatrix specialization.

Constructor & Destructor Documentation

  sc::RefSCMatrix::RefSCMatrix ()

Initializes the matrix pointer to 0. The reference must be initialized before it is used.

  sc::RefSCMatrix::RefSCMatrix (const RefSCDimension &d1, const RefSCDimension &d2, const Ref< SCMatrixKit > &)

Create a vector with dimension d1 by d2. The data values are undefined.

Member Function Documentation

  RefSCMatrix sc::RefSCMatrix::block (inti) const

If this matrix is blocked return block i. Otherwise return this as block 0.

  RefSCMatrix sc::RefSCMatrix::clone () const

These call the SCMatrix members of the same name after checking for references to 0.

  int sc::RefSCMatrix::nblock () const

If this matrix is blocked return the number of blocks. Otherwise return 1.

  double sc::RefSCMatrix::solve_lin (const RefSCVector &v) const

Solves this x = v. Overwrites v with x.

  void sc::RefSCMatrix::svd (const RefSCMatrix &U, const RefDiagSCMatrix &sigma, const RefSCMatrix &V)

Compute the singular value decomposition, this = U sigma V.t(). The dimension of sigma is the smallest dimension of this. U, V, and sigma must already have the correct dimensions and are overwritten.
