Default is `None`, which means using the zero initial guess. b : array_like right hand side Returns ------- (A, M, x, b, postprocess) A : LinearOperator matrix of the linear system M : LinearOperator preconditioner x : rank 1 ndarray initial guess b : rank 1 ndarray right hand side postprocess : function converts the solution vector to the appropriate type and dimensions (e.g. (N,1) matrix) rz&expected square matrix, but got shape=z shapes of A z and b z are incompatiblerr c|Srrrs r postprocessz make_system..postprocessQsrdtype)rpsolverpsolve)shaper)matvecrmatvecrz/matrix and preconditioner have different shapesMbz and x0 )rr" ValueErrorrrcharastypehasattrr#rrravelr rr!r rr isinstancestrcopyr) AMx0bA_Nrxtyper r!rbCopys r make_systemr6slB BAwwqzQWWQZA177*NOO  A1 A GG!u A4<yyA(() ) ww||6!
