It is shown that the equivalence of the Lanczos and the conjugate gradient algorithms can be used to give a very powerful method to study linear systems in which complex symmetric matrices arise. This method is illustrated for electron spin resonance calculations, but is applicable to a wide class of problems in physics and engineering.
