This function computes a change-of-basis matrix that converts from the truncated power basis to the B-spline basis. It is used by
coef.freekt and should not be called directly by the user.
The vector of knots. The first and last knots are repeated
The order of the spline, which is one more than the degree.
The change-of-basis matrix that converts from the truncated power basis to the B-spline basis.
