New Mathematica package and Math Arts
Let me inform Mathematica community about new Mathematica package
on Graph Tree Ltd. site http://www.graphtree.com/
Symbolic and numeric polynomial approximations:
(a) LDEs, functions
(b) initial and boundary value problems (IVPs, BVPs)
(d) BVPs and IVPs with regular singular points
1. 3D screensavers for Mathematica users (MathLogo 4,5 ...)
2. High quality desktop backgrounds (math themes)

...UTS discrete math packages: missing DiscreteMath package(s)
From MathSource, #4531, I downloaded the (rather old) "Discrete
Mathematics" packages in the form of the executable file
discretemaths.exe. When this is run it sets up a UTS directory with
various notebooks and packages. In directory UTS/Project there is a
notebook Master.nb which has an initialization cell that is supposed to
load DiscreteMath`Master`. But I find no such package.
Is there an entire subdirectory DiscreteMath missing from that distribution?
Note that there is a directory UTS/SetTheory.

in connection with my oo system for Mathemathica I implemented an
alternative method for calling functions in packages. The method is
especially important for calling the functions in objects, but it may also
be used outside objects, if the oo system is loaded.
The method has the advantage, that functions with the same name in different
packages may be used at the same time. No shadowing problems occur. The
contexts of the packages are not included in the context path.
The method is described in my documentation of the oo system on pages 4,5
on my web site:

Does somebody know why I get different behaviour for the following
commands in a commandline session of mathematica 7 or inside a notebook?
It also seems to be different in different Mathematica versions for the

Assuming one needs to have a function returning false or true on each
method as the basis of the pseudo-randomness. Say the variants of such
var n = Math.round(Math.random());
return n ? true : false;
var n = Math.floor(Math.random()*2);
return (n==2) ? true : false;
Leaving obvious practical testing by platforms aside:
Is there are theoretical considerations that pseudo-randomness
(predictability) of either of above will be better or worse than the

I've been asked by the 1076.1 (analog VHDL) for a matrix math package.
I put my first cut of a "real_matrix" package on line at:
This includes the package, package body and a short testbench. It still
needs some documentation, and probably a few more functions.
This is for type "real" only. Please tell me what you think.
Once we understand what is needed I can also do this with "signed" and

I taught a group of 32 smart high school kids some Mathematica this
week, at the Vermont Governor's Institute in Mathematical Sciences, aka
Math Camp. This is my second year doing it, and it's a ton of fun. I had
the kids an hour a day in one of our computer equipped classrooms, and
this year we added some additional optional computer time in the late
afternoons so they could come back and continue working / playing
around. (Last year some of them wanted more time, but there was no time
in the schedule when they could come back.)

I have built up a list of Java Math packages. A lot seem to have overlaping
