## In TeXForm

TeXForm parses this entry as prefix syntax; the package determines its argument specification.

### Expands to (physics)

```latex
\vnabla
```

→

```latex
{\gradientnabla}
```

This is the default branch because physics.arrowdel defaults to false. If the physics option arrowdel is true, the method reparses instead as \vec{\gradientnabla}.
