Whenever I am trying to compile the following code :

\documentclass[11pt,twoside,a4paper]{book}
\begin{document}
\begin{matrix*}[r]
-1 & 3 \\
2 & -4
\end{matrix*}  
 \end{document}

shows an error : Environment matrix* undefined.

I want to know what is the necessary package for

'bmatrix*,Bmatrix*,vmatrix*,Vmatrix*,pmatrix*,matrix* '

mathtools package, but I wonder how you could know those environments exist without seeing a document using that package?
