CyclicCont

This setting is based on the assumption that the motion profile given by the curve point list is continued cyclically in that P[n] = P[0] of the next cycle. This results in the same value for the derivative at both margins. The eInterpMode = "CyclicCont" setting is the default setting.

y'(P[0].X) = y'(P[n].X) = (P[1].Y - P[0].Y + P[n].Y - P[n-1].Y)) / (P[1].X - P[0].X] + P[n].X - P[n-1].X)

The following figure illustrates the procedure:
