Enclosing interface:

MatrixDecomposition<N extends Comparable<N>>

public static interface MatrixDecomposition.Hermitian<N extends Comparable<N>>
extends MatrixDecomposition<N>

Some matrix decompositions are only available with hermitian (symmetric) matrices or different decomposition algorithms could be used depending on if the matrix is hemitian or not.

Method Details

checkAndDecompose

default boolean checkAndDecompose(MatrixStore<N> matrix)

Absolutely must check if the matrix is hermitian or not. Then, depending on the result different paths can be chosen - compute or not / choose different algorithms...

Parameters:

matrix - A matrix to check and then (maybe) decompose

Returns:

true if the hermitian check passed and decomposition succeeded; false if not
