A variational procedure without the need of using L\* basis set expansion or trial wave functions is introduced for efficient and accurate treatment of relativistic quantum-mechanical eigenvalue problems. The method, ba>ed on the extension of the Fouriergrid Hamiltonian technique, is free from the p
