Albrecht,
The issue was to be able to define the transform t using its six components.

Hello Troy,
if you declare a transform variable (e.g., t), it works:
transform t;
t := identity rotated 270 yscaled 0.5;
show identity transformed t;
(0,0,0,1,-0.5,0)
Greetings

Well then in case anyone needs such a transformation, I've constructed the
(non-unique) transformation T

This yields T=(a,b,c,d,e,f).
