netket.optimizer.solver.cholesky

netket.optimizer.solver.cholesky(A, b, lower=False, x0=None)

Solve the linear system using a Cholesky Factorisation. The diagonal shift on the matrix should be 0.

Internally uses {ref}`jax.numpy.linalg.cho_solve`.

Parameters

• A – the matrix A in Ax=b

• b – the vector b in Ax=b

• lower – if True uses the lower half of the A matrix

• x0 – unused
