-      NOTE: once complex numbers are supported, each square matrix must be Hermitian.

     Parameters
     ----------
     x: array
-        input array having shape ``(..., M, M)`` and whose innermost two dimensions form square symmetric positive-definite matrices. Should have a real-valued floating-point data type.
+        input array having shape ``(..., M, M)`` and whose innermost two dimensions form square complex Hermitian or real symmetric positive-definite matrices. Should have a floating-point data type.
     upper: bool
-        If ``True``, the result must be the upper-triangular Cholesky factor ``U``. If ``False``, the result must be the lower-triangular Cholesky factor ``L``. Default: ``False``.
+        If ``True``, the result must be the upper-triangular Cholesky factor :math:`U`. If ``False``, the result must be the lower-triangular Cholesky factor :math:`L`. Default: ``False``.
 
     Returns
     -------
     out: array
-        an array containing the Cholesky factors for each square matrix. If ``upper`` is ``False``, the returned array must contain lower-triangular matrices; otherwise, the returned array must contain upper-triangular matrices. The returned array must have a real-valued floating-point data type determined by :ref:`type-promotion` and must have the same shape as ``x``.
