Comparisons with other CAS

General purpose, big "M" systems:
Maple, Macsyma, Mathematica, MuPAD

+	Large general-purpose functionality (simplification, solving, integration, differentiation, visualization)
-	Relatively slow for most "hard" computations (numerics, Groebner bases)
-	Restricted functionality in specialized areas (algebraic geometry)

Special purpose systems:
Groebner bases computations: Singular, Macaulay, Magma, CoCoA
Numerical computations: NAG library, Matlab

+	Very fast for specialized computations (Singular: 15sec; Mathematica/Maple: > 1000sec)
+	Extensive functionality in area of expertise
-	Functionality restricted to area of expertise (Singular can not plot curves and surfaces, has no trigonometric functions, can not simplify symbolic expressions)

Need to combine both:
