Constructing bivariate tensor product spline

Hello,
i have three vectors which contain the x, y, and z values of data points (x,y,z = [1xn]). Now i want to construct a tensor product splines out of these three vectors. I found an example but i'm not sure how to use this example with my input data. Can anyone help me please. Thanks

What do the x,y,z vectors represent in you application?
Depending on the kind of surface (I assume it is a surface what you are seeking) you want to obtain you will need one preprocess or another. Once you have your data in a suitable shape then you can apply some tensor product approximation to them.
