Atoms

The Mole Package contains 3 mfiles and 1 matfile. molecules2 calculates molecular masses pertable provides data on the elements sym2an converts a chemical symbol to a valid atomic number (useful for molecules2 and pertable). atoms contains atomic number data.

NanoVis (beta version) allows to visualize any atomistic structure by reading a user defined file. The supported formats are "gen" and "xyz". There are two display modes: normal and "spacefill". In the zip file, with the .m file, there are two examples of structure and a file containing the atoms...

initializePhysicalConstants.m loads important physical constants into the structure CONSTS. The CONSTS structure will contain both values (accessible by CONSTS.var_name), and descriptive information (CONSTS.desc.var_name.[Name, Units, Value]).EXAMPLE USAGE: % What are the units of the unversal...
