How can I recenter a map

Hi,

I created a map using pcolor. The map has longitudes starting from 0 to 360. I want that the map starts from -180 to +180 that the greenwch will be the center of the map.

The map come from a necdf file with latitudes, longitudes and precipitation.

map=pcolor(map_longitude,map_latitude,precipitation_change)
