 Description The center of gravity of the vector Y = f(X) is calculated according to the formula: COG = sum( Yi * Xi ) / sum( Yi ). It is assumed that the values of Y represent point masses, situated at the positions given by X. If all elements of X are 0, there is no mass and no gravity; nevertheless, the center of gravity is assumed as the mid-point of X, i.e. (X[size-1] - X[0]) / 2. To calculate the center of gravity of a vector over its indices as the abscissa, call VF_centerOfGravityInd.
 Error handling none
 Return value The (interpolated) position of the center of gravity on the X axis is returned.
