Interp3d 3D interpolation from raw data
=Interp3d(Method, Scaling, x0Values, x1Values, x2Values, fValues,
x0Star, x1Star, x2Star, SubKriging)
Parameters
Method: Interpolation method
- 0 = Nearest-neighbor
- 1 to 1.99 = Kriging (1.5 is a good choice)
Scaling: Scaling of parameters
- 0 = If parameters are homogeneous (no scaling)
- 1 = If parameters are NOT homogeneous (e.g. for black box model)
x0Values: Function first parameter values
x1Values: Function second parameter values
x2Values: Function third parameter values
fValues: Function values
x0Star: First parameter value(s) to interpolate
x1Star: Second parameter value(s) to interpolate
x2Star: Third parameter value(s) to interpolate
SubKriging: [Optional for Kriging i.e. if 1 ≤ Method ≤ 1.99]
- If positive = Number of nearest points to select (4 ≤ SubKriging ≤ 1024, SubKriging = 256 is a good choice)
- If negative = −Distance for selection of nearest points (SubKriging < 0)
If the SubKriging parameter is missing, all points will be used for Kriging interpolation.
If Scaling = 1, the distance for selection of nearest points is calculated in the normalised space (see main page for details).
