About the presentation of matrix

  1. Jun 9, 2012 #1
    I have a problem about the matrix,
    i try the following tex commands:
    ##A=\begin{ bmatrix } 1 & 2 \\ 3 & 6 \end{ bmatrix }##

    and it can not show the matrix, I don't know what is the problem, since the
    code style seems right. And another problem is I try to use Daum Equation Editor
    to edit the math equation, but the problem is if I add $ and $ surround the code
    paste from Daum Equation Editor, it can not show the result I want.
    it will show the original codes without any compile. Is any possible solution for that,
    thanks a lot.

    Here is a LaTeX guide: https://www.physicsforums.com/showthread.php?t=546968

    In your case, you should not type spaces before and after bmatrix. It should be

    Code (Text):

    ##A=\begin{bmatrix} 1 & 2 \\ 3 & 6 \end{bmatrix}##
    which gives

    ##A=\begin{bmatrix} 1 & 2 \\ 3 & 6 \end{bmatrix}##
