Introduction to solve_rec (Maxima 5.47.0 Manual)

88.1 Introduction to solve_rec

solve_rec is a package for solving linear recurrences with polynomial coefficients.

A demo is available with demo("solve_rec");.

Example:

(%i1) load("solve_rec")$

(%i2) solve_rec((n+4)*s[n+2] + s[n+1] - (n+1)*s[n], s[n]);
                                    n
                 %k  (2 n + 3) (- 1)          %k
                   1                            2
(%o2)       s  = -------------------- + ---------------
             n     (n + 1) (n + 2)      (n + 1) (n + 2)
