In the documentation for AnyKinPointSurface it says that the normed measure is calculated as
I have two questions relating to this calculation:
Is this last log supposed to be read as “log(Exponent) times d_i” or as “log base Exponent of d_i”?
If I measure distances individually and then try to calculate the normed measure “by hand”, it is different from the value I get from AnyBody. This is no matter which of the two calculations mentioned in 1) I use. For instance: in one frame I have four distances (0.0329, 0.0244, 0.0254, 0.0297) with Base 1.0 and Exponent 20. Using “log(Exponent) times d_i” I get 0.451 and using the other calculation I get 0.862. From AnyBody I get -0.4347 (note the minus). Any ideas why?
