gcm

Current map projection structure

Syntax

mstruct = gcm
mstruct = gcm(hndl)

Description

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

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

Examples

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

axesm mercator
mstruct = gcm

Tips

You create map structure properties with the axesm function. You can query them with the getm function and modify them with the setm function.
