# skfolio.utils.stats.is_cholesky_dec ### skfolio.utils.stats.is_cholesky_dec(x) Returns True if Cholesky decomposition can be computed. The matrix must be Hermitian (symmetric if real-valued) and positive-definite. No checking is performed to verify whether the matrix is Hermitian or not. * **Parameters:** **x** *ndarray of shape (n, m)* : The matrix. * **Returns:** **value** *bool* : True if Cholesky decomposition can be applied to the matrix, False otherwise.
