Compute the first derivative at each point of a signal. The first and last data points become DATA_NOT_FOUND (identified in the C3D file as a POINT Reliability value of &endash;1).
Derivatives are calculated using Finite Difference Algorithms.
Given the signal:
x(ti) for i=1, 2, …, n The first derivative is calculated using: xDot(ti)= (x(ti+1)-x(ti-1))/( (ti+1)-(ti-1) )
