   lenskit.math.solve.solve_cholesky



Module Contents
---------------

.. py:function:: solve_cholesky(A, y)

   Solve the system :math:`A\mathbf{x}=\mathbf{y}` for :math:`\mathbf{x}`
   with Cholesky decomposition.

   This wraps :func:`torch.linalg.cholesky_ex` and :func:`torch.cholesky_solve`
   in an easier-to-use interface with error checking.

   :param A: the left-hand matrix :math:`A`
   :param y: the right-hand vector :math:`\mathbf{y}`

   :returns: the solution :math:`\mathbf{x}`
