Nonuniform Spline Dictionaries:

  • CutDic produces a non-uniform B spline dictionary
  • NonBSpline Computes the value of B spline basis at x0 by the recurrence formula for the non-uniform B spline
  • NonUniB computes all non-unfirom B spline over the partition 'p'
  • ProducePartition using the curvature of the signal f, it compute the knots of a partition
