The I-Spline basis functions are the integrals of the M-splines, or alternatively the integrals of the B-splines normalized to the range [0,1]. Every I-spline basis function increases monotonically from 0 to 1, thus it is useful as a basis for monotone functions. An I-Spline curve is monotone if and only if every non-zero control point has the same sign.
iSpline :: Knots (Scalar a) -> Vector a -> ISpline aSource
iSpline kts cps
creates an I-spline with the given knot vector and control
points. The degree is automatically inferred as the difference between the
number of spans in the knot vector (numKnots kts - 1
) and the number of
control points (length cps
).
