Our PREP workshop people are chugging along through our tutorial. However, several of them - all using XP (and no snarky comments, I doubt they can just ask their universities to give them a new Linux box) are getting TinyMCE boxes with just the 'save changes' and 'cancel' buttons, but the box itse

As an electrical engineer by training and currently working on statistics, I too find the lack of support for generalized distributions in the general-purpose math packages ... disturbing. Their definitions essentially reach out from the integrand and modify the limits of integration, it is not so

RJF's point is the one that has been on my mind as I try to come up to speed on this discussion. TeX formulae are written to generate some graphical effect; their algebraic structure is some combination of accident and good style, not anything that the language forces on the author. You can't exp

You might want to make your own thread ;-) My new ATLAS spkg will be much friendlier to build. It can also more easily use the OS-provided ATLAS libraries. In particular, I'm using them all the time on Fedora. Amazon probably doesn't include the libraries in their base install, but you could pr

You are piping strings to/from GAP, are you? Depending on how often you end up using GAP internally you might be interested in a shared-library interface to GAP. We do have an experimental one, see http://trac.sagemath.org/sage_trac/ticket/6391 Volker -- To post to this group, send an email
