正則行列と逆行列

<div style="padding-left: 2em">
[tex:
A = \left(
  \begin{array}{ccc}
    1 & 1 \\
    0 & 2
  \end{array}
  \right)
B = \left(
  \begin{array}{ccc}
    1 & 0 \\
    0 & 1/2
  \end{array}
  \right)
]
</div>

特に意味のないelisp

(defun insert-hatena-latex-markdown ()
  (interactive)
  (insert "<div style=\"padding-left: 2em\">") (newline)
  (insert "[tex:") (newline)
  (insert "]") (newline)
  (insert "</div>") (newline)
  )
