gcm (Mapping Toolbox)

Get current map structure

Syntax

```
mapstruct = gcm
mapstruct = gcm(hndl)
```

Description

mapstruct = gcm returns the map axes map structure, which contains the settings for all the current map axes properties.

mapstruct = gcm(hndl) specifies the map axes by axes handle.

Examples

Establish a map axes with default values, then look at the structure:

axesm mercator
mapstruct = gcm
mapstruct =

Remarks

Map structure properties are created with the axesm command. They can be queried with the getm command and modified with the setm command.
