simpeg.optimization.InexactCG#
- class simpeg.optimization.InexactCG(*, cg_rtol=0.1, cg_atol=0, cg_maxiter=5, **kwargs)[source]#
- Bases: - object- Mixin to hold common parameters for a CG solver. - Parameters:
 - Attributes - Absolute tolerance for inner CG iterations. - Maximum number of CG iterations. - Relative tolerance for inner CG iterations. - InexactCG.maxIterCG has been deprecated. - InexactCG.tolCG has been deprecated. - See also - Notes - The convergence check for CG is: >>> norm(A @ x_k - b) <= max(cg_rtol * norm(A @ x_0 - b), cg_atol)
