I need to define a rather complex operation. Hence I want to use the classical "where" definition style, i.e.
Foo = Bar(x,y)
WHERE
x = Baz
y = Fob
My attempt so far in latex is:
\begin{align*}
\text{Foo} = \text{Bar}(x,y) && \mathbf{where} \\
x = \text{Baz}
\end{align*}
I am not really satisfied with the result, though:
- The where keyword does not really stand out from the layout
- The helper definitions are on the same level as the main definition
So instead of fiddling around with it, is there some kind of (semi-) canonical way to layout such definitions?

I'm guessing you're using the
\text
macro to typeset stuff in roman font, but that's bad pratice because semantically incorrect: the\text
macro should be reserved for typesetting phrases such as "where", "for all", "subject to", etc. within display math environments (e.g.equation
,align
, etc.), not for variables or function names. You should use the\mathrm
macro, instead, here.Here's how I would write your equations:
