Vector.elements(array, copy = true)
Vector.basis(size: n, index: k)
Vector.zero(n)

To access elements:

#[](i)

To enumerate the elements:

#each2(v)
#collect2(v)

Properties of vectors:

#angle_with(v)
Vector.independent?(*vs)
#independent?(*vs)
#zero?

Vector arithmetic:

#*(x) "is matrix or number"
#+(v)
#-(v)
#/(v)
#+@
#-@

Vector functions:

#inner_product(v), dot(v)
#cross_product(v), cross(v)
#collect
#magnitude
#map
#map2(v)
#norm
#normalize
#r
#round
#size

Conversion to other data types:
