1 | ```
aSolver(z, a, extra)
``` |

`z` |
Vector containing observed response |

`a` |
Matrix with active constraints |

`extra` |
List with element |

This function is called internally in `activeSet`

by setting `mySolver = aSolver`

.

`lbd` |
Vector with Lagrange multipliers |

`f` |
Value of the target function |

`gx` |
