An algorithm for generating the B-spline basis is given in de Boor (1978, pp. 134 -135). B-splines are both a computationally accurate and efficient way of constructing a basis for piecewise ...
The difference between PSPLINE and BSPLINE is that PSPLINE produces a piecewise polynomial, whereas BSPLINE produces a B-spline. A matrix consisting of a piecewise polynomial basis and an intercept ...
