Worldmap plot with data

Hello!!I am a very beginner in Matlab and I am trying to make the contour of temperature anomaly data that are in a 4D matrix(longitude,latitude,month,year) with a world map on the background. The problem is that the longitude of these data goes from 0-360 and matlab world maps usually go from -180 to 180. Is there an effective way to make the coastline going from 0-360, using the latitude and longitude data that i have and not the default ones??Im using a 2014b Matlab. I was also trying to find a way to do that with the Map_M toolbox of Matlab but i could not change it.Is there maybe a way through it??Thank you in advance!

The code below will create a map axes, set the longitude limits to 0 to 360 and plot the coastlines on the map. Note that the Meridian Labels will now display as 0 to 360 E.
%create the map axes. See http://www.mathworks.com/help/map/the-map-frame.html
axesm('MapProjection','robinson',...
'MapLatLimit',[-90 90],'MapLonLimit',[0 360], ...
'Frame','on','Grid','on', 'MeridianLabel', 'on', 'ParallelLabel', 'on')
%load the coast data and plot. See http://www.mathworks.com/help/map/create-a-world-map.html
load coast
[latcells, loncells] = polysplit(lat, long);
numel(latcells)
plotm(lat, long)
