Abstract
We propose a simple acceleration technique for the calculation of the electronic structure, based on the singular value decomposition. The efficiency and accuracy of the present approach are demonstrated in the case of the energy bands and overlap integrals of wurtzite ZnO determined with the empirical pseudopotential method.
