Derivative - Differentiation

Derivative - Creates a new curve, which represents a differential curve of the selected channel. The method is based on calculating the Cubic Spline and analytic derivation of the calculated polynomial. For input parameters this method uses a number of points inserted between every two adjacent points and an array of differentials for them. A Zero differential represents its Cubic Spline. It is possible to calculate, at most, the differential of the third order, of the starting curve.
