Class Summary |
Algebra |
Linear algebraic matrix operations operating on DoubleMatrix2D ; concentrates most functionality of this package. |
CholeskyDecomposition |
For a symmetric, positive definite matrix A, the Cholesky decomposition
is a lower triangular matrix L so that A = L*L';
If the matrix is not symmetric or positive definite, the constructor
returns a partial decomposition and sets an internal flag that may
be queried by the isSymmetricPositiveDefinite() method. |
EigenvalueDecomposition |
Eigenvalues and eigenvectors of a real matrix A. |
LUDecomposition |
For an m x n matrix A with m >= n, the LU decomposition is an m x n
unit lower triangular matrix L, an n x n upper triangular matrix U,
and a permutation vector piv of length m so that A(piv,:) = L*U;
If m < n, then L is m x m and U is m x n. |
LUDecompositionQuick |
A low level version of LUDecomposition , avoiding unnecessary memory allocation and copying. |
Property |
Tests matrices for linear algebraic properties (equality, tridiagonality, symmetry, singularity, etc). |
QRDecomposition |
For an m x n matrix A with m >= n, the QR decomposition is an m x n
orthogonal matrix Q and an n x n upper triangular matrix R so that
A = Q*R. |
SeqBlas |
Sequential implementation of the Basic Linear Algebra System. |
SingularValueDecomposition |
For an m x n matrix A with m >= n, the singular value decomposition is
an m x n orthogonal matrix U, an n x n diagonal matrix S, and
an n x n orthogonal matrix V so that A = U*S*V'. |
