java equivalent of scipy.linalg.eigh with parameter optional matrix

I need calculate eigenvalue in java. And I need the relative matrix which is like the parameter b in scipy.linalg.eigh.

def eigh(a, b=None, lower=True, eigvals_only=False, overwrite_a=False,
     overwrite_b=False, turbo=True, eigvals=None, type=1,
     check_finite=True, subset_by_index=None, subset_by_value=None,
     driver=None):

Method description
Solve a standard or generalized eigenvalue problem for a complex
Hermitian or real symmetric matrix.

Find eigenvalues array ``w`` and optionally eigenvectors array ``v`` of
array ``a``, where ``b`` is positive definite such that for every
eigenvalue λ (i-th entry of w) and its eigenvector ``vi`` (i-th column of
``v``) satisfies::

                  a @ vi = λ * b @ vi
    vi.conj().T @ a @ vi = λ
    vi.conj().T @ b @ vi = 1

In the standard problem, ``b`` is assumed to be the identity matrix.

Parameters
----------
a : (M, M) array_like
    A complex Hermitian or real symmetric matrix whose eigenvalues and
    eigenvectors will be computed.
b : (M, M) array_like, optional
    A complex Hermitian or real symmetric definite positive matrix in.
    If omitted, identity matrix is assumed

I have tried apache.math. All of them only offer the similar eig method without parameter. Is there any equivalent in java?
