#### Dim

-- Option variable: dim Default value: 4

An option in the `ctensor` (component tensor) package. `dim` is the dimension of the manifold with the default 4. The command `dim: n` will reset the dimension to any other value `n`.

There are also some inexact matches for `dim`. Try `?? dim` to see them.

```(%o1)                                true
(%i2) ```
