Vector(VBasis& b, ScalarList& a)
This creates a vector in the space containing the basis b with the coordinates given in the list of scalars.
Vector(VSpace& ins, GeObList& s) Vector(VSpace& ins, GeOb& v1, GeOb& v2) Vector(VSpace& ins, GeOb& v1, GeOb& v2, GeOb& v3)
These constructors build a vector tuple in the specified cartesian product vector space ins. The elements of the tuple are either given by the objects in the list s (for the first constructor), or individually (the other two constructors). The elements are first cast into vectors or affine vectors, if necessary.
