[math] documentation for what pseudo-inverse means in decomp solvers

2013-10-18 Thread Phil Steitz
The decomposition solvers can "invert" non-square matrices. There is no documentation describing what exactly is being returned in these cases. It is not obvious to me exactly what conditions the returned value satisfies in each case when the actual parameter is not square. Do all of them return

Hello All, What tool is used to create the documentation (if one is used at all)? Specifically, I am looking in commons-math/src/site/xdoc/userguide If I wanted to add to the regression portion of stat.xml what is the best way to accomplish this (use vi or some wysiwyg editor)? Thank you, -Greg
