This function computes a inverse of a real symmetric or complex hermitian positive-definite matrix using Cholesky factorization. If matrix ``a`` is not positive definite, Cholesky factorization fails and it raises an error. Args: a (cupy.ndarray): Real symmetric or complex hermitian maxtix. Returns: cupy.ndarray: The inverse of matrix ``a``. rlapack)cupyxrr_assert_cupy_array _assert_2d_assert_stacked_squarestacked_identity_likeposv)arbs M/home/wildlama/miniconda3/lib/python3.13/site-packages/cupyx/linalg/_solve.pyinvhr sR Q Q   # ##A&A ;;q cSSKJn UupVU(aU(a$[R"URSS5O#[R "URSS5n[ R"USUSUS45R5(d [S5e[ R"U5R5(d [S5eU(dsURS:Xa2URR(a[ R"USS S 9nO1URR(a[ R"US S S 9nURXQUS 9$) ak Solves the linear system Ax = b using the Cholesky factorization of A. Batched input arrays are also supported. Args: c (tuple of cupy.ndarray and bool): The first tuple item is the Cholesky factor of the matrix `A`, typically obtained from `cupy.linalg.cholesky`. The second item is a bool that indicates whether the Cholesky factor is stored in the lower-triangular part (when True) or in the upper-triangular part (when False). b (cupy.ndarray): Right-hand side array. overwrite_b (bool, optional): If True, the contents of `b` may be overwritten for efficiency. Default is False. check_finite (bool, optional): If True, checks whether the input arrays contain only finite numbers. Disabling this may improve performance but can lead to crashes or non-termination if NaNs or infs are present. Default is True. Returns: cupy.ndarray: Solution to the linear system Ax = b. See Also: cupy.linalg.cho_factor: Computes the Cholesky factorization. Examples: >>> import cupy as cp >>> from cupy.linalg import cholesky, cho_solve >>> A = cp.array([[9, 3, 1, 5], ... [3, 7, 5, 1], ... [1, 5, 9, 2], ...
