Hi there, I have been using the Tps function (within the Fields package) for a while now to interpolate different sedimentary units. Due to the method of formation of the units I know that at some edges the thickness of the unit decreases to zero. I was wondering if there was someway to specify that the interpolation only occurs within the convex hull of the data, outside of which the the values are zero. I am having prob...

Hello there, I am using the Tps function to fit a spline to my data which is measurements of a sedimentary layer on an xy plane to see how the thickness of the layer changes. I was wondering if it was possible to change the Tps code so that no minus values are calculated by the spline as these are obviously unfeasible. Any help would be much appreciated, Thanks, Sam -- View this message in context...
