∥ (parallel to)
Checks if two vectors are parallel.
u ∥ v
vare vectors of the same dimension
v are vectors of the same dimension, then
u ∥ v is
v are parallel, that is, iff there exists a scalar
κ such that
u = κ⋅v or
v = κ⋅u.
∥ operator is implemented by the
AreParallel function. This function also supports a third argument specifying the epsilon to use for floating-point comparison.
