∦ (not parallel to)

Checks if two vectors are not parallel.

Syntax

• u ∦ v

  • u and v 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 floating-point comparison.

Examples

❨3, 1, 2❩ ∦ ❨−2, 5, 1❩
