| Description | Y(t) = dX(t) / dt.
The vector X is assumed to be a function of a variable t; the t values themselves are equally spaced. Therefore, only the spacing, DeltaT, must be passed to the function. By parabolic interpolation, the derivative of X with respect to t is calculated. This function does the inverse of the integration by VF_runintegralC. |
