CsApprox2dTab 2D Cubic Spline Approximation from tabulated data
=CsApprox2dTab(NbPointsPerCell, SplineSensitivity, Scaling, x0Values,
x1Values, fValues, x0Star, x1Star)
Parameters
NbPointsPerCell: Average number of points per cell e.g. = 5 works best for uniform data decrease to get smaller cells or increase to get larger cells
SplineSensitivity: Spline sensitivity e.g. = 140, reduce to get smoother results
Scaling: Scaling of parameters
- 0 = If parameters are homogeneous (no scaling)
- 1 = If parameters are NOT homogeneous (e.g. for black box model)
x0Values: Row of function first parameter values
x1Values: Column of function second parameter values
fValues: Table of function values
x0Star: First parameter value(s) to interpolate
x1Star: Second parameter value(s) to interpolate
