Spot operator: opSpot/cgs | Spot Home Page |
CGS Conjugate Gradients Squared Method. X = cgs(A,B) attempts to solve the square linear system A*X=B via the CGS method. This routine is simply a wrapper to Matlab's own CGS routine, and the argument list variations described in Matlab's CGS documentation are also allowed here. The usage is identical to Matlab's default version, except that the first argument must be a Spot operator.
