l2 Penalized Nonlinear Minimization

Sparse digital signal Generator with given thresholds.

1 | ```
sparseSignal(N, s, b = 1, delta = 1e-07, nlev = 0.05, slev = 0.9)
``` |

`N` |
Number of signal components, vector size. |

`s` |
Number of spikes, significatn components |

`b` |
Signal bandwidth, defaults 1. |

`delta` |
Length of discrete distances among components, defaults 1e-7. |

`nlev` |
Maximum value of insignificant component, relative to b, defaults to 0.05 |

`slev` |
Maximum value of significant component, relative to b, defaults to 0.9 |
