Draw the matrix using MarkDown

I’m going to need a matrix for my essay today, so make a note

Drawing matrices requires special syntax

(1) Draw the ordinary matrix, without parentheses

?
 \begin{matrix}
   a & b & c & d & e\\
   f & g & h & i & j \\
   k & l & m & n & o \\
   p & q & r & s & t
  \end{matrix} 
?
Copy the code

(2) Draw the matrix with brackets

?
\left[
 \begin{matrix}
   a & b & c & d & e\\
   f & g & h & i & j \\
   k & l & m & n & o \\
   p & q & r & s & t
  \end{matrix} 
\right]
?
Copy the code

(3) Draw the matrix with braces

?
\left\{
 \begin{matrix}
   a & b & c & d & e\\
   f & g & h & i & j \\
   k & l & m & n & o \\
   p & q & r & s & t
  \end{matrix} 
\right\}
?
Copy the code

(4) Add a parameter before the matrix

$$A=
\left\{
 \begin{matrix}
   a & b & c & d & e\\
   f & g & h & i & j \\
   k & l & m & n & o \\
   p & q & r & s & t
  \end{matrix} 
\right\}
?
Copy the code

(5) There are ellipses in the middle of the matrix

//\cdots = horizontal ellipsis //\vdots = vertical ellipsis //\ddots = oblique ellipsis $$A=
\left\{
 \begin{matrix}
   a & b & \cdots & e\\
   f & g & \cdots & j \\
   \vdots & \vdots & \ddots & \vdots \\
   p & q & \cdots & t
  \end{matrix} 
\right\}
?
Copy the code

(6) Add the root line in the middle of the matrix

/ / array must be an array / / {CCCC | c} c said in the matrix elements, can control the position of the | $$A=
\left\{
 \begin{array}{cccc|c}
     a & b & c & d & e\\
     f & g & h & i & j \\
     k & l & m & n & o \\
     p & q & r & s & t
  \end{array} 
\right\}
?
Copy the code

Hope I can help you
