Any maths buffs?

Yeh me too. Here's whats happening,

I've extracted some data from a netCDF file (this took me long enough to figure out), and it's in matrix form with each element containing a location in latitude and longitude along with the temperature at that point. I can currently get matlab to plot the temperature in pure grid form if the matrix was evenly distributed across the globe but i can't figure out how to get it to locate each point to the lat and lon associated with it. I'm doing all this with the mapping tool box.

No worries if you can't figure it out, I'll just ask someone when I next go into uni.

persevere with matlab. it's a great tool.
you need to sort your data into 3x 2d vectors (lat, long, temp)
use
axesm('mercator')
pcolorm(lat,long,temp);
demcmap(temp);

can't test this as i no longer have a license - check here for more details about pcolorm
