  If all you want to do is to be able to "easily" handle a set of values
as if they were a matrix, you could create a 2-dimensional array from them:

http://povray.org/documentation/view/3.6.1/233/

  Note, however, that POV-Ray offers no native matrix operations (such
as addition, multiplication, etc) doable to such "matrix" arrays, so if
you need those operations you'll have to implement them yourself. This
should be more or less trivial to do using #macros.
