Enumeration Type Documentation

Property

enum dftefe::linearAlgebra::LAPACKSupport::Property

A matrix can have certain features allowing for optimization, but hard to test. These are listed here.

Enumerator
general	No special properties.
hermitian	Matrix is symmetric.
upper_triangular	Matrix is upper triangular.
lower_triangular	Matrix is lower triangular.
diagonal	Matrix is diagonal.
hessenberg	Matrix is in upper Hessenberg form.

State

enum dftefe::linearAlgebra::LAPACKSupport::State

Most of the LAPACK functions one can apply to a matrix (e.g., by calling the member functions of this class) change its content in some ways. For example, they may invert the matrix, or may replace it by a matrix whose columns represent the eigenvectors of the original content of the matrix. The elements of this enumeration are therefore used to track what is currently being stored by this object.

Enumerator
matrix	Contents is actually a matrix.
inverse_matrix	Contents is the inverse of a matrix.
lu	Contents is an LU decomposition.
cholesky	Contents is a Cholesky decomposition.
eigenvalues	Eigenvalue vector is filled.
svd	Matrix contains singular value decomposition,.
inverse_svd	Matrix is the inverse of a singular value decomposition.
unusable	Contents is something useless.
