Hi, I am looking for a function (library) that allows evaluation of a B-spline basis (specified by the knots and the order), at given points, _and_ also allows the evaluation of derivatives for the same family. R's splineDesign in the splines package has this, but looking at the splines libraries in Julia I could not find one that does B-splines and derivatives. Using internals from some library would be fine, too.
(Knowing that there is no such thing at the moment would also be useful, I might implement it, but would prefer to avoid that because B-spline special cases are tricky). Best, Tamas
