AreNotParallel
Checks if two vectors are not parallel.
Syntax

AreNotParallel(u, v[, ε])

u
andv
are vectors of the same dimension 
ε
is the epsilon to use for floatingpoint comparison

Description
If u
and v
are vectors of the same dimension, then AreNotParallel(u, v)
is true
iff u
and v
are not parallel, that is, iff there is no scalar κ
such that u = κ⋅v
or v = κ⋅u
. The specified value of ε
will be used as the epsilon for floatingpoint comparisons. If not specified, a default epsilon will be used.
Notes
The ∦
infix operator is implemented by the AreNotParallel
function. This operator doesn’t support a custom epsilon.
Examples
❨3, 1, 2❩ ∦ ❨−2, 5, 1❩
true
AreNotParallel(❨3, 1, 2❩, ❨6, 2, 4.001❩, 1E−2)
false
