Library libhftohoyn1 (version 0.3) is a software library written in C++ for Hartree-Fock computations for atoms using interpolating wavelets. In addition, there are functions to solve the radial Schrödinger equation of the hydrogen atom for the ground state and excited states using interpolating wavelets. Libhftohoyn1 uses liboctave, see Octave website, for vector and matrix computations. Handling diagonal Lagrange multipliers (needed to preserve orthogonality of the orbitals for open-shell atoms) is not implemented. See this publication for the theory.
Example programs for libhftohoyn1 are included in
hftohoynexamples (version 0.3)
This package contains HF computations for helium, lithium, beryllium,
neon, sodium, magnesium, and argon, and solving Schrödinger equation
of hydrogen ground state and excited states.
