What is the exact meaning of the dSmoothness (Smoothness factor)
in the Curve_derivative or similar functions ?
How is it set best ?

Thanx
Alex

If I remenbered correctly, Origin firstly call internally a nag function to get the cubic spine approximation. The dSmoothness is to control the closeness between the data and the fit.After the spline is obtained, then it will get the derivatives. As how to choose the dSmoothness, you can take a look at http://www.nag.com/numeric/CL/manual/pdf/E02/e02bec.pdf
Hope it will help.
