Hello everybody,
it seems that my last mail has failed to reach this mailing list. So here
agein:
I do the following in maxima:
First some initialisation...
> y : x1$
> d1y : x2$
the following is clear.
> concat(d,1,y)
=> d1x1
the following is also clear.
> concat(d,1,'y)
=> d1y
now comes the problem
> ev(concat(d,1,'y),eval)
=> d1x1
How can I change the last command to get x2?
Why does maxima first set x1 for y in, before the concat is evaluated?
Thanks
Christian
