John - thank you, 'springs' seems to be doing the job!

Bruno - you can use trapz twice: http://blogs.mathworks.com/loren/2011/06/13/calculating-the-area-under-a-surface/

30 Oct 2012 Surface Fitting using gridfit Model 2-d surfaces from scattered data Author: John D'Errico

Lovely function - just one question, is it possible to put constraints on the range of values that zgrid can take please? for example, I'm using this to create a surface for a motor rpm/torque/efficiency map (which I am then querying with interp2 to provide an efficiency estimate for a given speed and loading), but every now and then I find that some of the zgrid values are negative. I could set these to zero using find, but I'm hoping to find(!) something a little more elegant!
