Hi!
Function range() was only present in wxMaxima. It was an undocumented
function, so officialy it was never part of Maxima. It was removed,
because there is another range() function in some share package
(statistics related) which does something completely different.
Ofcourse range() in other languages (python? mathematica) means a
list of integers...
Looks like you'll have to use makelist or create your range function:
range(a,b):= makelist(i, i, a, b)$
I'd rather see a range() function similar to one in Mathematica but
my experience of trying to improve upon some basic Maxima functions
tells me that it's not going to happen. It's the "slow-grinding wheel
of Maxima", that prevents any improvements.
