I want to get an interpolation. My aim is to get the z[i] for x[i] and y[i] which are between the values in the excel spreadsheet (e.g. z[i] for x[i]=87 and y[i]=63). Since the data are material properties the calculated z[i] must be "between" the surrounding data points. The Fit in the statistics package calculates the parameters for a model function. But I am not sure how to provide the best (or at least a suitable) parametric model function.

Maple creates with surfdata 3D surface plots. My idea was to get the z[i] for any x[i], y[i] (in the range of the data points) from this surface plot.

Thanks again!

Thanks again!

is it correct that you added two times the same file (.ind and no .lib)?

I work with Maple 11, which does not include the Surfplot-package. I have checked this in the package library. I thik this is a new feature of Maple 12.

After executing your worksheet (8933_data2.mw), Maple 11 returns the following error message after the command "with(Surfplot)":

"Error, invalid input: with expects its 1st argument, pname, to be of type {package, module}, but received Surfplot"

Therefore following commands of your worksheet does not work in Maple 11:

1. RemoveEquals
2. Triangulate

your suggestion is working well, but unfortunately the "Surfplot" Package is only available within Maple 12!

Thanks for the hint with polygonplot3d! I am still a bit displeased with the "incomplete" borders. Restructuring the basic data source did not work, but I did not want to add any data points.
