Re : Regression / Channel function

[Ayane]

Hello !

I want to estimate a value from the 3D table in attached.

For example : if i have X = 600 and Y = 0,2 so Z = 1492, this example works well, but if I have X = 900 and Y = 0,14 I have to estimate the value of Z.

Is there a way with DIAdem functions to estimate Z point, with a regression equation ?

Hello Ayane,

The function "ChnD3InterpPoint" calculates the Z value for given X/Y values. It is based on a triple structure. So in your case you need to confert the matrix structure into a triplet structure (3D basic functions in ANALYSIS).

Thanks ! It works well !
