JmatrixLMA | R Documentation |

Calculate the Jacobian matrix with the original dataset and the
current version of fitted data. This is not intended for
external use. It is called from `fitConic`

```
JmatrixLMA(XY, parA, XYproj)
```

`XY` |
The original input dataset |

`parA` |
The current set of ABCDEF quadratic equation coefficients. |

`XYproj` |
The current calculated dataset based on the latest iteration of the coefficient set. |

`Res ` |
residuals based on the norm of XY - XYproj |

`J ` |
matrix of values for each input data point corresponding to the terms in the general quadratic Ax^2 + Bxy + Cy^2 +Dx + Ey +F |
