I am new to Maple 13, I have a data set that I can fit a b-spline curve to and out put the polynomials. I plot the the curve but I want the predicted values of the curve so I can compare them to other predicted values from other programs (eg SAS). I want to plot all the curves from each program in Excel against to actual values. Here is my worksheet for reference: Loading CurveFitting Loading plots Loading plottools
