Abstract: Algorithms for the explicit symbolic and numeric evaluation of Jacquet's Whittaker function for the $ GL(n,\mathbb{R})$ based generalized upper half-plane for $ n\ge 2$, and an implementation for symbolic evaluation in the Mathematica package GL(n)pack, are described. This requires a comparison of the different definitions of Whittaker function which have appeared in the literature.
