[texhax] 3x3 array of alighned equations

I'd like to format a 3x3 array of subequations in the form:
a11 = b, a12 = c, a13 = d (1a,b,c)
a21 = f, 3 x a22 = ... (1d,e,f)
a22 = .. (1g,h,i)
i.e. I want them aligned horizontally between the three columns and also I want them aligned to the = sign within each column. So I effectively have 9 columns, or 3 columns each with 3 subcolumns. The eqnarry environment only allows the alignment to work with one equation per line, and the array environment typesets fractions in a tiny font so that they fit within one text line. However, I want them to be at full size like in an ordinary equation. I have a hack for getting the subequation numbering to work without using the subequations environment so that shouldn't be a drama. If there is a way to produce an array that allows left/centre/right alignment and also allows fractions to be typeset at full size then that would almost certainly work.
Any tips would be great!
