I have the free maxima 5.12
can I solve a linear finite difference equation,
in a symbolic way, with Maxima?
For example, if I give to Maxima the input:
x(n+1)+x(n)=0
then Maxima have to give me the output:
x(n)=c*(-1)^n. (where c depends on initial condition).
The package solve_rec can solve some difference equations.
load (solve_rec);
solve_rec (x[n] + x[n + 1]=0, x[n]);
=> x[n] = %k[1]*(-1)^n
I think solve_rec is in Maxima 5.12. If not just
get a later version.
There might be another package for difference equations,
I don't remember for sure.
