Do a union of polygons and add the associated values for overlapping coordinates

I have 6 matrices of lat, Lon and power values. 3 of them have the same size for lat, lon and power. The other 3 have the same matrix size for lat, lon and power. But different size from the other coordinates. So they both form a polygon would power values but one polygon is bigger and there some overlap. I wanted to do a union between the coordinates and where ever the lat and lon overlap, add the power values together.Since the data are matrices, I tried to convert them into vectors to do a polyshape of lats and lons and do a union after. But that does not seem to work. Well I don’t know for sure because one of the matrices is too big and took forever to be converted into a vector.
Poly1 =polyshape(lat1,lon1); Poly2 = polyshape(lat2,lon2); polyout =union(Poly1,Poly2);
Since polyshape function does not take a 3rd variable I have not figured how to add the power values together for overlapping coordinates. Is there any other approach I can take to achieve that.
