suitable Regression or Curve fitting for vertical scattered Data

Hi everyone,

I have some vertical scattered Data. But I can not find a suitable cure fitting the Data. Does anybody have an idea? Is there any possiblity to get a good aproximated curve from such scattered data?

Best Regards

Have you tried using the Scattered Data Interpolation functions? You can find more information here:

Additionally, the Curve Fitting Toolbox may have some helpful functionality:

If so and they have not worked, could you provide the data or a plot of it and why these methods have not worked for you?

I guess you can try regression using artificial neural network (ANN):

Or you can go for some techniques in statistics and machine learning toolbox...
