The first link below is a big klugy table. It is meant to be a (mostly) complete listing, in alphabetical order, of the routines that are actively used in most of my work. The remaining links and text explain broad topics, but they also link back to the code documentation given in my fundamental (Big) table. The ordering of these topics can change regularly, depending on the emphasis of my current work. A lot of older documenets have become obsolute, but they may have historical value and are available through the last link in the list below.
