I feel I must be missing something fundamental...
How do you write a function (or ?) in Mathematica which produces more
than one output?
Let's say I have some data and I want a single function to calculate the
mean, variance, std, etc, more than one thing and return those? I know
that there are builtin functions for those parameters, but the point is
I want to define functions with more than one output.
The only examples I can find are along the lines of:
which have only a single result.
Is there a different structure altogether, such as a Subroutine, which
allows multiple results from a single subunit?
One thought I had was that because Mathematica treats everything as
global unless defined specifically local (e.g. in a module), that
variables used in a procedure would be accessible and would thus be a
"result", but it seems scoping problems would arise if this was used too
often. For example:
Is this the accepted method for extracting multiple results from one
