In mathematics, given a vector space X with an associated quadratic form q, written (X, q), a null vector or isotropic vector is a non-zero element x of X for which q(x) 0. In the theory of real bilinear forms.
In mathematics, given a vector space X with an associated quadratic form q, written (X, q), a null vector or isotropic vector is a non-zero element x of X for which q(x) 0. In the theory of real bilinear forms, definite quadratic forms and isotropic quadratic forms are distinct. They are distinguished in that only for the latter does there exists a nonzero null vector. A quadratic space (X, q) which has a null vector is called a pseudo-Euclidean space.
From CRAN documentation: NULL represents the null object in R: it is a reserved word. NULL is often returned by expressions and functions whose value is undefined. But your question can still have learning opportunities with respect to lists. It will show up there. As in: Vlist <- list(1, 2, 3, NULL, 5). Trying to identify the NULL value in a very large dataset can be tricky for novice R users. There are different techniques, but here is one that worked for me when I needed it. !unlist(lapply(vlist, i. umeric)) FALSE FALSE FALSE TRUE FALSE Or as user Kara Woo added.

So null vector has magnitude . 0 and certain direction which is arbitrary. A vector is represented by direction and magnitude. If we take the number 0, it has no magnitude, and it can be given any sign.
So null vector has magnitude . Similarly, null vector, also known as zero vector has no magnitude but can be given a direction. A vector with zero magnitude but the certain direction is known as a null vector. If a→ is a vector than a→ 0. It means that the vector is pointing in a certain direction but is still there.
