In friendly/matlib: Matrix Functions for Teaching and Learning Linear Algebra and Multivariate Statistics

title: "R Markdown: Display a Matrix for R Variable" author: "Romain Lesur" output: html_document: keep_md: true

This is from: StackOverflow

A = matrix(c(1,3,0,1),2,2)
B = matrix(c(5,3,1,4),2,2)

Now, matrix are rendered as LaTeX:

Matrix A in inline mode: $\begin{bmatrix} 1 &0 \3 &1 \ \end{bmatrix}$

Matrix A in display mode:

$$\begin{bmatrix} 1 &0 \3 &1 \ \end{bmatrix}$$

Operators

As other answers suggested, it could be useful to define operators. With the previous class, it is relatively straightforward:

Example in inline mode: $\begin{bmatrix} 1 &0 \3 &1 \ \end{bmatrix} + \begin{bmatrix} 1 &0 \3 &1 \ \end{bmatrix} \times \begin{bmatrix} 5 &1 \3 &4 \ \end{bmatrix}$

Display mode: $$\begin{bmatrix} 1 &0 \3 &1 \ \end{bmatrix} \times \begin{bmatrix} 5 &1 \3 &4 \ \end{bmatrix}$$
