[SIESTA-L] Numerical radial shape

2009-05-13 Thread John Appleton
Dear users,   After reading the siesta papers, I clearly understand the concept of atomic-like orbitals (radial function times spherical harmonics). However, I don't quite understand the phrase the radial shape of every orbital is numerical. Can someone kindly give me a simple explanation?
