How do I calculate b-form spline interpolation?
This page says I can use csapi but that does not seem like the right function. Using the curve fit toolbox it would be ideal if I can convert smoothing spline into b-form.

The “ppmak” function allows you to create a piecewise polynomial by specifiying a strictly increasing list of breaks
To convert to and from B-form and ppform, You can use the fn2fm function
You can refer to below link for more information
Hope it helps.
