fhyp | R Documentation |

These functions are not intended for external use.
`fhyp`

and `fhypopt`

support the parent function `bootHyperbola`

by providing functions for `optimize`

to use.
The functions `costparab`

`costparabxy`

similarly provide functions for `optim`

to use inside the function `fitParabola`

.

```
fhyp(xy, b3, Ang)
costparabxy(theta, xy)
costparab(theta, xy)
```

`xy` |
A Nx2 array of data |

`b3` |
Three of the parameters describing a hyperbola. These three are the "other parameters" fed to |

`Ang` |
The initial angle of rotation, also optimized during the process. |

`theta` |
The angle of rotation of the parabola for this run of |

various combinations of "cost" values, i.e. Figure of Merit, to determine optimal set of coefficients, along with datasets where necessary. ..
