coordsys.names - Function

1.1.3 Recover the names for each axis


Description

Each axis associated with the Coordinate System has a name (they don’t mean anything fundamental). This function returns those names in world axis order.

You can recover the names either for all coordinates (leave type unset) or for a specific coordinate type (mimumum match of the allowed types will do). If you ask for a non-existent coordinate an exception is generated.

You can set the names with function setnames.
