Don't worry about it, Tom - neither do I apparently.

Quite right. I originally kept the name as coeffs then decided to change the name to recurs and completely and utterly messed up the edit and, even worse, the checking. When, when, when will I ever learn. (that's rhetorical, by the way, or partially ... can't decide whether it's t = 1/0 or t = 1.0/0.0)
>On my system (2001i) the last function does not evaluate symbolically. I thought that was still failing in 11 -- has it been fixed?
The entire worksheet evaluates symbolically in 11.1
The real reasons for the original worksheet in this thread not working seem to be that the symbolic processor doesn't like:
a. evaluating z as constructed - it whines pitifully about the matrix dimensions being incompatible; using a range variable to create z helps.
b. when that's corrected, evaluating regress.
