http://www.ccas.ru/ca/lqrs?rev=1518776110&do=diff
The LqRS (Linear q-Recurrence Systems) package implements in Maple 2017 a family of algorithms to solve a full-rank q-recurrence system.
We consider an arbitrary order linear system S of q-recurrence equations with polynomial coefficients:
An(x) y(x q^n) + … + A1(x) y(x q) + A0(x) y(x) = b(x),text/html2018-01-06T12:48:57+02:00saconference - [Conference Materials]

http://www.ccas.ru/ca/lrs?rev=1507962181&do=diff
The procedure HypergeometricSolution in the package LRS (Linear Recurrence Systems) is an implementation in Maple 2015 of an algorithm to construct a basis of the space of hypergeometric solutions for systems of difference equations with polynomial coefficients.
The algorithm is based on the use of resolving sequences.
