A B C D E F G H I J K L M N O P Q R S T U V W X Y Z overview

For an invertible linear map $ v\mapsto Av$ the inverse of matrix $ A$ is denoted by $ A^{-1}$, that is,

$\displaystyle A A^{-1} = A^{-1} A = E
$

where

$\displaystyle E = \left(\begin{array}{cccc}
1 & 0 & \cdots & 0 \\
0 & 1 & \c...
... \\
\vdots & 0 & \ddots & \vdots \\
0 & & \cdots & 1
\end{array}\right)
$

is the identity matrix.
