We can create a matrix in LaTeX using the array environment, or simplematrix, matrix, pmatrix, bmatrix, vmatrix, and Vmatrix environments via amsmath package. This article provides some examples on how to create a matrix in LaTeX.
Creating a matrix with array
Here are some examples.
-
unbracketed matrix
\[
M =
\begin{array}{cc}
x & y \ z & w \ \end{array}
\]
-
matrix surrounded by square brackets
\[
M =
\left[ {\begin{array}{cc}
x & y \ z & w \ \end{array} } \right]
\]
-
matrix surrounded by parentheses
\[
M =
\left( {\begin{array}{cc}
x & y \ z & w \ \end{array} } \right)
\]
-
matrix surrounded by single vertical lines
\[
M =
\left| {\begin{array}{cc}
x & y \ z & w \ \end{array} } \right|
\]
Using amsmath package
Call \usepackage{amsmath} in the preamble, after \documentclass{}.
The amsmath package environment for matrix:
-
smallmatrix: inline matrix
$M = \begin{smallmatrix} x&y\\ z&w \end{smallmatrix}$
$M = \left( \begin{smallmatrix} x&y\\ z&w \end{smallmatrix}\right)$
-
matrix: unbracketed matrix
$M = \begin{matrix} x&y\\ z&w \end{matrix}$
-
pmatrix: matrix surrounded by parentheses
$M = \begin{pmatrix} x&y\\ z&w \end{pmatrix}$
-
bmatrix: matrix surrounded by square brackets
$M = \begin{bmatrix} x&y\\ z&w \end{bmatrix}$
-
vmatrix: matrix surrounded by single vertical lines
$M = \begin{vmatrix} x&y\\ z&w \end{vmatrix}$
-
Vmatrix: matrix surrounded by double vertical lines
$M = \begin{Vmatrix} x&y\\ z&w \end{Vmatrix}$
