Detailed Description

The RefSymmSCMatrix class is a smart pointer to an SCSymmSCMatrix specialization.

Constructor & Destructor Documentation

sc::RefSymmSCMatrix::RefSymmSCMatrix ()

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

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

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

Member Function Documentation

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

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

RefSymmSCMatrix sc::RefSymmSCMatrix::clone () const

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

void sc::RefSymmSCMatrix::diagonalize (const RefDiagSCMatrix & eigvals, const RefSCMatrix & eigvecs) const

Sets eigvals to the eigenvalues and eigvecs to the eigenvalues and eigenvectors of the referenced matrix. The result satisfies eigvecs * eigvals * eigvecs.t() = (*this).

int sc::RefSymmSCMatrix::nblock () const

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

double sc::RefSymmSCMatrix::solve_lin (const RefSCVector &) const

Solves this x = v. Overwrites v with x.
