 Description The center of gravity of the vector X is calculated according to the formula: COG = sum( Xi * i ) / sum( Xi ). It is assumed that the values of X represent point masses, situated at the positions given by their indices. The center of gravity is returned as a real number, as it will normally fall in between of two adjacent indices. 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. (size-1) / 2. To calculate the center of gravity of a vector over an abscissa explicitly given (rather than over its indices), call VF_centerOfGravityV.
 Error handling none
 Return value The position of the center of gravity is returned.
