A Maple Vector is an rtable with subType option Vector.

The type(expr, Vector) function returns true if expr is a Maple Vector.

The type(expr, 'Vector'(R)) function returns true if expr is a Maple Vector with the shapes or options given in R (see Vector for permissible shapes and options), or if the entries of expr have the type R, in case R is a type.

Note:  It is essential to quote the word Vector in this form of the calling sequence in order to avoid confusion with the Vector(..) constructor function.
