I'd like to integrate a symbolically defined indicator function:
W(x,y) = t < abs(x-y) < 1-t
though it seems our symbolic objects don't work with chained
inequalities, so I'd be happy with
W(x,y) = (t < abs(x-y)) * (abs(x-y) < 1-t)
Even the following doesn't work:
sage: x,y,t = var('x,y,t')

See also the Sage versions of Python's range() and xrange(): srange()
and xsrange().
E.g.
sage: srange(1,10,2)
[1, 3, 5, 7, 9]
sage:
still new to sage noticed that most plots had that listed to show the
intervals between the range. Thanks for the info.

Just curious:
Any reason to use [0,1,..3] instead of just [0..3] or even the pure
Python syntax: range(4) ?

Hola!
I experimented almost a complete day with the seemingly simple
problem, I want to program a simple function, like:
f(u,v)=\cases{ 2, if u>=v,
0, else.}
and similar functions. As I want tom do calculus, I need symbolic
expressions, not Python functions.
I tries using

It does limit the total number of build jobs within the current make. Of
course

FWIW, slightly off-topic:
