CG on the Normal Equations, CGNE and CGNR

     

The CGNE and CGNR methods are the simplest methods for nonsymmetric or indefinite systems. Since other methods for such systems are in general rather more complicated than the Conjugate Gradient method, transforming the system to a symmetric definite one and then applying the Conjugate Gradient method is attractive for its coding simplicity.
