Rewrite patterns#

1. vectorunit\vectorunit{#1}\vu{#1}
2. vectorunit-star\vectorunit*{#1}\vu*{#1}

Examples#

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

\vectorunit{e}_r\cdot\vb{r}=r

\vu{e}_r\cdot\vb{r}=r

\vectorunit*{\alpha}\cdot\vectorunit*{p}

\vu*{\alpha}\cdot\vu*{p}

Notes#

Star is preserved on the short alias; physics StarMacro propagates it into the nested vb branch used under hat.
