latex matrix code example

Example 1: matrix latex

\begin{bmatrix}
1 & 2 & 3 \\
a & b & c \\
a & b & c \\
\end{bmatrix}

Example 2: matrix latex

\begin{equation*}
A_{m,n} = 
\begin{pmatrix}
a_{1,1} & a_{1,2} & \cdots & a_{1,n} \\
a_{2,1} & a_{2,2} & \cdots & a_{2,n} \\
\vdots  & \vdots  & \ddots & \vdots  \\
a_{m,1} & a_{m,2} & \cdots & a_{m,n} 
\end{pmatrix}
\end{equation*}

Example 3: latex pmatrix

Trying to typeset an inline matrix here
$\begin{pmatrix}
  a & b\\ 
  c & d
\end{pmatrix}$ 
but it looks too big, so let's try 
$\big(\begin{smallmatrix}
  a & b\\
  c & d
\end{smallmatrix}\big)$ 
instead.

Example 4: how to make matrix latex

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\begin{document}
$$
\begin{bmatrix} 
a & b & c \\
c & d & d\\
e & f & g \\
\end{bmatrix}
\quad
$$
\end{document}

Example 5: how to write a matrix latex

\documentclass{article}
\usepackage{amsmath}
\begin{document}

\[
M=
  \begin{bmatrix}
    1 & 2 & 3 & 4 & 5 \\
    3 & 4 & 5 & 6 & 7
  \end{bmatrix}
\]

\end{document}

Example 6: latex matrix

% Plain matrix
\begin{matrix}
	1 & 2 & 3\\
	a & b & c
\end{matrix}

% Parantheses matrix
\begin{pmatrix}
	1 & 2 & 3\\
	a & b & c
\end{pmatrix}

% Square bracket matrix
\begin{bmatrix}
	1 & 2 & 3\\
	a & b & c
\end{bmatrix}

% Braces matrix (curly brackets matrix)
\begin{Bmatrix}
	1 & 2 & 3\\
	a & b & c
\end{Bmatrix}

% Pipes
\begin{vmatrix}
	1 & 2 & 3\\
	a & b & c
\end{vmatrix}

% Double pipes
\begin{Vmatrix}
	1 & 2 & 3\\
	a & b & c
\end{Vmatrix}
