Examples#

Each example shows this rule applied in isolation. A complete normalization profile may make additional changes.

\begin{pmatrix} a & b \\ c & d \end{pmatrix}

\left(\begin{matrix} a & b \\ c & d \end{matrix}\right)

\begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix}

\left(\begin{matrix} 1 & 0 \\ 0 & 1 \end{matrix}\right)

\pmatrix{x \cr y}

\pmatrix{x \cr y}
