Hi.
I'm trying to permute some functions w.r.t. the variables they are
using.
For example, I have a function
(C93) f:u-v+3*w;
(D93) 3 w - v + u
then, I "rotate" the vars like this:
(C94) f:f,u=v,v=w,w=u;
(D94) - w + v + 3 u
which is what I want.
But how can I achive it within a function. If I go
func(p):=( .. stuff ...
f:u-v+3*w,
... stuff ..
f:f,u=v,v=w,w=u,
... stuff that uses the new f...
)
the substitutions seem to have no effect. The subst functions seems
only to allow one substitution at a time, so I can't use it, it seems.
Help appreciated
Thanks
Neilen
