Detailed Description

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


Constructor & Destructor Documentation

◆ RefSymmSCMatrix() [1/2]

sc::RefSymmSCMatrix::RefSymmSCMatrix ( )

Initializes the matrix pointer to 0.

The reference must be initialized before it is used.

◆ RefSymmSCMatrix() [2/2]

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

◆ block()

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

If this matrix is blocked return block i.

Otherwise return this as block 0.

◆ diagonalize()

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).

◆ nblock()

int sc::RefSymmSCMatrix::nblock ( ) const

If this matrix is blocked return the number of blocks.

Otherwise return 1.

◆ solve_lin()

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

Solves this x = v.

Overwrites v with x.
