It is proved that the evaluation of the Coulomb potential and the calculation of its matrix elements can be carried out in separate steps whose costs formally increase as the square of the number of basis functions. The resulting method for computing the Coulomb matrix is reported, and its main features are tested with a trial program for Slater functions. A comparison of the Coulomb matrices obtained...
