Worldmap function is not working?

I'm trying to create a simple map displaying the locations of various climate monitoring stations, using the following code:

%%

figure(4)

clf

worldmap world

load coastlines

plotm(coastlat,coastlon,'k-')

loc=find(in_Tropics_mask);

plotm(metadata.Lat(loc),metadata.Lon(loc),'k.','markersize',15)

However, I keep getting the following error:

Undefined function 'worldmap' for input arguments of type 'char'.

Any help would be appreciated.

The worldmap function is part of Mapping Toolbox. Check the output of the ver function to see if you have this toolbox installed.
