Trace Interpolation is different from ordinary interpolation since it interpolates the curve based on the index of X coordinate rather than adjacent data points in the X coordinate. When the curve is cyclic or periodic, it is more appropriate to use trace interpolation rather than ordinary interpolation. Choose from one of three methods: Linear, Cubic Spline and Cubic B-Spline.
Controls recalculation of analysis results
