CutoffRadius is an option to ConnectionList. The value Infinity is default. If the distance between two point is larger than 2 times the CutoffRadius value, the two points are not connected. Remember, that the DistanceMatrix function represents the squared distances, so the matrix values are compared to 4 times the CutoffRadius value squared.
CutoffRadius is also an option to InterpolationCoefficients and to Interpolation when Method→"ObtuseAngle" is specified. The interpolated value is not affected by the function value in control points that are more distant than the CutoffRadius value. |
