# Vector Component

(Redirected from vector component)
• QUOTE: Let $\R^n$ denote the vector space of real n-vectors: :$x \in \mathbb{R}^n \Leftrightarrow \ \ x = \begin{bmatrix} x_{1} \\ \vdots \\ x_n \end{bmatrix} \ \ x_i \in \R.$ We refer to $x_i$ as the ith component of $x$. Depending upon context, the alternative notations $[x]_i$ and $x(i)$ are sometimes used.
