# Highly Nonlinear Approximations for Sparse Signal Representation

# Matlab Files

## 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

All the presented routines are described in detail in our manual (ps,pdf).
