lsie_ln | R Documentation |

solve linear least square problem (min ||A%*%x-b||)
with inequality constraints u%*%x>=co and equality constraints e%*%x=ce
Method:
reduce the pb to lsi_ln on the null-space of e

```
lsie_ln(a, b, u = NULL, co = NULL, e = NULL, ce = NULL, rcond = 1e+10)
```

`a` |
dense matrix A or its QR decomposition |

`b` |
right hand side vector |

`u` |
dense matrix of inequality constraints |

`co` |
right hand side vector of inequality constraints |

`e` |
dense matrix of equality constraints |

`ce` |
right hand side vector of equality constraints |

`rcond` |
maximal condition number for determining rank deficient matrix |

solution vector whose attribute 'mes' may contain a message about possible numerical problems
