B_Spline

Companion object B_Spline

class B_Spline extends BasisFunction with Error

The B_Spline class provides B-Spline basis functions for various orders 'm', where the order is one more than the degree. A spline function is a piecewise polynomial function where the pieces are stitched together at knots with the goal of maintaining continuity and differentiability. B-Spline basis functions form a popular form of basis functions used in Functional Data Analysis.

def abf_(m: Int = mMax)(t: Double): VectorD
Evaluate each of the τ.dim-1-many order m B-spline basis functions at t non-recursively, using an efficient dynamic programming approach.
Evaluate each of the τ.dim-1-many order m B-spline basis functions at t non-recursively, using an efficient dynamic programming approach.
Example
```
val m = 4                       // order m (degree m-1)
val t = VectorD (1, 2, 3, 4)    // original time points
val N = B_Spline (t, k)         // B_Spline instance
val z = N.abf_ (m)(t)           // vector of evaluations
println ("order k basis functions at t = z")
```
Implementation Details
Let N(m)(i) denote the i-th order k basis function evaluated at t. Then each N(m)(i) depends on the evaluation of N(m-1)(i) and N(m-1)(i+1). Here is an example, given a set of order m=4 B-spline basis functions and knot vector τ of length n:
```
N(1)(0), N(1)(1), N(1)(2), N(1)(3), ..., N(1)(n-1)
      |/       |/       |/            |/

N(3)(0), N(3)(1), ..., N(3)(n-3)
      |/            |/
