23 Jan 2012 Free-knot spline approximation Least squares approximation of 1D data using free-knots spline Author: Bruno Luong

Hey Bruno thanks for the awesome package, it works great!
I just have one problem, is this approximation rotation invariant? Since when I intentionally rotate my data points the knots are completely different with increased fit error compared to the baseline profile! please let me know if I am doing sth wrong
