Radias Basis Function CS 21

Altair Forum User

Hi,

 

at the moment i have lot of data an try to investigate, if it is possible to approximate this data and to get to know,

what's the correlation between these Parameters.

If I use Radial Basis Functions mit RBF Type 'CS21' in Hyperstudy 12, I get good R-Square values for the Validationsmatrix

and therefore a satisfying approximation.

Unfortunately, if I search for 'CS21' in the Hyperworks Desktop or anywhere else, I'm not able to find any Infomation

what this RBF Type is. Does anybody know what type of Basis Functions the option 'CS21' uses?

 

Thanks in advance!

Thanks for pointing this out. We will work to add this information to the online help. In the meantime, CS21 stands for Wu's compactly supported (2,1). I cannot see to be able to paste the function here. You can find it in Handbook of Digital Homan Modeling, Chapter 21 or in math.iit.edu.
