AffineTransform[m] gives a TransformationFunction that represents an affine transform that maps r to m.r. AffineTransform[{m, v}] gives an affine transform that maps r to m.r ...
Apart
(Built-in Mathematica Symbol) Apart[expr] rewrites a rational expression as a sum of terms with minimal denominators. Apart[expr, var] treats all variables other than var as constants.

(Built-in Mathematica Symbol) Catalan is Catalan's constant, with numerical value \[TildeEqual] 0.915966.
Convergents[list] gives a list of the convergents corresponding to the continued fraction terms list.Convergents[x, n] gives the first n convergents for a number ...
Cross
(Built-in Mathematica Symbol) Cross[a, b] gives the vector cross product of a and b.
Denominator[expr] gives the denominator of expr.
Equivalent[e_1, e_2, ...] represents the logical equivalence e_1 \[DoubleLeftRightArrow] e_2 \[DoubleLeftRightArrow] ..., giving True when all of the e_i are the same.
EulerGamma is Euler's constant \[Gamma], with numerical value \[TildeEqual] 0.577216.
MatchingDissimilarity[u, v] gives the matching dissimilarity between Boolean vectors u and v.
MatrixQ
(Built-in Mathematica Symbol) MatrixQ[expr] gives True if expr is a list of lists or a two-dimensional SparseArray object that can represent a matrix, and gives False otherwise. MatrixQ[expr, test] gives ...
