Detailed Description

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

---

Constructor & Destructor Documentation

RefSCMatrix::RefSCMatrix ( )

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

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

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

Solves this x = v. Overwrites v with x.

void 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.
