∦ (not parallel to)
Checks if two vectors are not parallel.
Syntax

u ∦ v

u
andv
are vectors of the same dimension

Description
If u
and v
are vectors of the same dimension, then u ∦ v
is true
iff u
and v
are not parallel, that is, iff there exists no scalar κ
such that u = κ⋅v
or v = κ⋅u
.
Notes
The ∦
operator is implemented by the AreNotParallel
function. This function also supports a third argument specifying the epsilon to use for floatingpoint comparison.
Examples
❨3, 1, 2❩ ∦ ❨−2, 5, 1❩
