Hi,
I would also look into the ArrayExtension
(http://www.mediawiki.org/wiki/Extension:ArrayExtension)
If you have something like
[[HeightLength::1;4]]
[[HeightLength::2;5]]
you can extract and assign a HeightArray and a LengthArray by queries (see
examples on extension page).
Unfortunately the ArrayExtension doesn't implement the array_map function but it
shouldn't be too difficult to add something like #arraymap which would use PHP's
array_map() function with the given parameters.
And than something along the line
{{#arraydefine:SquareArray|
{{#arraymap:HeightArray|LengthArray|'function($l,$h){return(0.5*$h*$l);}' }}
would return an array of the results.
Cheers,
Gu
