If you are asking what the "prediction equation" looks like, it
might be expressed most compactly in matrix terms, as suggested
by what David posted.  His equation seems to describe the whole problem.

But in more familiar terms, it would be written out somewhat like
two regression equations, with a terms for the levels of the factors
and their interactions on the right; and two Y variables on the left. 
With two degrees of freedom on the left and more on the right,
there will be at least two roots to the canonical correlation problem.

All,

 

A colleague asked me what should be a simple question and I have no answer for him.  He has some basic manova syntax (below) and he would like to know what the equation from such a model would look like.  Excluding all of the marginal means, etc., can anyone answer that question for him?  Thanks very much.
