Here is a simple one, but I can't work it out. I would like to be able to define a function this way: z=mat[[1]][[1]] a + mat[[1]][[2]] without specifying what "mat" is explicitly. I would evaluate it later this way: z/.mat->somePredefinedMatrix Of course, Mathematica complains about the definition (Part specification mat[[1]] is longer than depth of object) ... is there a way to make this fly? Thanks, Aram Schiffman
