I just installed STIX on my workstation, and I have to say, MathML rendering in Firefox of the NIST DLMF is incredible good - in some cases better than their PNG images for non-mathml browsers (e.g. http://dlmf.nist.gov/7.7 ).

If you have a favourite professional American baseball team, and you don't want to download 100MB in baseball data to do the computation above.  Ask, and I can run them when I get a chance.

These are known as favicons.

While it may be more efficient for some simple cases, signum (which does its main work in `signum/main`) calls `is` to do its work.

It should be noted that the conditions can be simplified: the `and` is unnecessary since piecewise branches are evaluated from first to last:

Compare:

(**) n:=3;
(**) simplify(  piecewise(seq(op([q-1<=t and t<q, f[q](t+1-q)[i][j]]),q=1..n), 0) );

(**) piecewise(t<0, 0, seq(op([t<q, f[q](t+1-q)[i][j]]),q=1..n), t>=n, 0);

This appears to be a bug in the '!!!' button.  I will make sure it is reported.

Just to expand a little.  It is possible to discover the equivalence of "find" and ?ArrayTools[SearchArray] using ?Matlab,FromMatlab

(**) Matlab:-FromMatlab("find(X)", evaluate=false);
#                          ArrayTools:-SearchArray(X)

Ah! I tried every possible entry method except 1-D input in Document mode.

I can't replicate this in my local install of Maple 14 in 64 bit Linux:

Download printlevel_test.mw

What platform are you using?

I can't seem to replicate this as a bug. In Maple 14,

solve({b4*y^3+b1*x*y^2+b2*x^2*y+b3*x^3, a*y+a1*x+a2*x*y+a3*x^2+a4*y^2}, {x,y});

gives me the same answer as Maple 13 in both 32 and 64 bit Linux.  Are you on a different platform?
