BasisVector

Returns a standard basis vector in ℝⁿ.

Syntax

• BasisVector(n, k)

  • n is a positive integer

  • k is a positive integer in [1, n]

Description

If n is a positive integer and k a positive integer in [1, n] ∩ ℤ, then BasisVector(n, k) returns the kth standard basis vector in ℝⁿ.

Examples
