Question: Evaluating Data


I have some numerical data (-> data2.txt) for a velocity profile (x- and y- coordinate with corresponding velocity). I would like to compare this data with a analytical function (3D plot -> Maple file).

Do anybody know, how

#1 to get the data - points in the 3D plot and

#2 how to determine the error between the data - points and the 3D plot?
