Interface MatrixDecomposition.Hermitian<N extends Number>

All Superinterfaces:

MatrixDecomposition<N>

All Known Subinterfaces:

Cholesky<N>, Eigenvalue<N>, LDL<N>

All Known Implementing Classes:

HermitianEvD

Enclosing interface:

MatrixDecomposition<N extends Number>

public static interface MatrixDecomposition.Hermitian<N extends Number>
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 Detail

checkAndCompute

default boolean checkAndCompute(MatrixStore<N> matrix)

Absolutely must check if the matrix is hermitian or not. Then, depending on the result differents 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 computation suceeded; false if not
