%description
Build and use B-splines for interpolation and regression. In case of
regression, equality constraints as well as monotonicity and/or positivity
of B-spline weights can be imposed. Moreover, knot positions (not only
spline weights) can be part of optimized parameters too. For this end,
'bspline' is able to calculate Jacobian of basis vectors as function of
knot positions. User is provided with functions calculating spline values
at arbitrary points. These functions can be differentiated and integrated
to obtain B-splines calculating derivatives/integrals at any point.
B-splines of this package can simultaneously operate on a series of curves
sharing the same set of knots. 'bspline' is written with concern about
computing performance that's why the basis and Jacobian calculation is
implemented in C++. The rest is implemented in R but without notable
impact on computing speed.
