LaTeX matrix generator

Set the number of rows and columns, type the values or paste a block of cells from Excel, pick the brackets and copy the code. Matrices up to 10 x 10, with a preview that shows how it will look in the PDF.

A = \begin{pmatrix} 1 & 2 \\ 3 & 4 \end{pmatrix}

LaTeX code

\[
A = \begin{pmatrix}
1 & 2 \\
3 & 4
\end{pmatrix}
\]

Type numbers or LaTeX expressions, e.g. \frac{1}{2}. Enter moves to the cell below; paste a block of numbers from a spreadsheet into the first cell.

How it works

Each bracket type is its own amsmath environment: pmatrix ( ), bmatrix [ ], vmatrix | | for a determinant, Vmatrix ‖ ‖ for a norm, Bmatrix { } and matrix without brackets.
A block of cells pasted from a spreadsheet is spread over rows and columns starting at the cell you paste into.
A decimal comma is written as {,}, because a plain comma in math mode adds a space: 2{,}5 prints like 2,5.
Cells accept regular LaTeX, such as \frac{1}{2} or \pi, and the matrix name (e.g. A or B^T) goes before an equals sign.

Matrix bracket types

Environment	Looks like	Use it for
`pmatrix`	$\begin{pmatrix} a & b \\ c & d \end{pmatrix}$	the most common matrix notation
`bmatrix`	$\begin{bmatrix} a & b \\ c & d \end{bmatrix}$	square brackets, common in physics and computer science
`vmatrix`	$\begin{vmatrix} a & b \\ c & d \end{vmatrix}$	a determinant
`Vmatrix`	$\begin{Vmatrix} a & b \\ c & d \end{Vmatrix}$	a matrix norm
`Bmatrix`	$\begin{Bmatrix} a & b \\ c & d \end{Bmatrix}$	curly braces
`matrix`	$\begin{matrix} a & b \\ c & d \end{matrix}$	bare values, e.g. inside your own brackets

Packages you need

\usepackage{amsmath}  % pmatrix, bmatrix, vmatrix
