∦ (not parallel to)
Checks if two vectors are not parallel.
u ∦ v
vare vectors of the same dimension
v are vectors of the same dimension, then
u ∦ v is
v are not parallel, that is, iff there exists no scalar
κ such that
u = κ⋅v or
v = κ⋅u.
∦ operator is implemented by the
AreNotParallel function. This function also supports a third argument specifying the epsilon to use for floating-point comparison.
