Let us say we have a vector $\vec v$, I have seen in numerous places the notation $[\vec v]_B$ used to denote the vector $\vec v$ written in a particular basis $B$. With analogous notation been used for matrices. Does this notation have a particular name?

What is this notation called; $[\vec v]_B$?
