Pre-allocated state for the Conjugate Residual solver.

See LinearSolverState for the constructor parameters. The preconditioner M may be freely changed (or toggled between None and a valid operator) between calls as long as the matrix shape, batch count, dtype, and device remain the same.

Parameters:

• A (array | BsrMatrix | LinearOperator)

• b (array)

• x (array)

• tol (float | None)

• atol (float | None)

• maxiter (float | None)

• M (array | BsrMatrix | LinearOperator | None)

• callback (Callable | None)

• check_every (int)

• use_cuda_graph (bool)

Parameters:

• A (array | BsrMatrix | LinearOperator)

• b (array)

• x (array)

• tol (float | None)

• atol (float | None)

• maxiter (float | None)

• M (array | BsrMatrix | LinearOperator | None)
