Current map projection structure
mstruct = gcm
mstruct = gcm(hndl)
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.
Establish a map axes with default values, then look at the structure:

You can query them with the getm function and
modify them with the setm function.
