A few months ago, Michael Wester made a review  of the mathematical
capabilities of different computer algebra systems, namely Axiom, Derive, Macsyma,
Maple, Mathematica and Reduce.
This review, which is available by anonymous ftp
consists of 131 tests in different
domains of mathematics (arithmetic, algebraic equations, differential equations,
integration, operator computation, series expansions, limits).
We describe in this paper the problems that can be solved with MuPAD 1.2.2, and how to solve them. The problems marked as [New] are solved using new functionalities of the version 1.2.2 with respect to 1.2.1.
