=Interp4d(Method, Scaling, x0Values, x1Values, x2Values, x3Values, fValues,
x0Star, x1Star, x2Star, x3Star, SubKriging)
Method: Interpolation method
Scaling: Scaling of parameters
x0Values: Function first parameter values
x1Values: Function second parameter values
x2Values: Function third parameter values
x3Values: Function fourth 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
x3Star: Fourth parameter value(s) to interpolate
SubKriging: [Optional for Kriging i.e. if 1 ≤ Method ≤ 1.99]
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).
