Hi... I don't have a lot of experience with Maple, but I want to plot some test data and find a least squares curve fitting. I know how to plot the stuff I want to plot, and how to do basic least square fitting. However, I have 6 data points to apply least squares on, and I have one additional "fixed" point. I know the curve will have to become parabolic (And I know how to curve fit to that using LeastSquares), but the problem is that the minimum of that parabola has to go through the fixed point. I have no idea how to achieve this (if it is at all possible).
