3 dimensional interpolation.

I have a data set consisting of 3D cartesian coordinates and in order to perform double integration, I need to make my x and y data to be uniformly distributed. How can I achieve this if there is no equation relating x and y to their respective z value?

Make an interpolation function from your data and call "integral2" with this function as to be integrated within specified limits.

Here is the way to generate the interpolation function:
