Title: | Rcpp Interface to Hyper-Dual Numbers |
---|---|

Description: | Hyper-Dual Numbers permit the exact calculation of second derivatives which is both free of truncation and subtractive cancellation. Hyper-Dual numbers were introduced Jeffrey Fike and Juan Alonson, and this package uses a header-only C++ implementation by Fike and released under the MIT license. Accurate 2nd derivatives computation. |

`addHD( c(1,2,0,0), c(2,-1,0,1))`

`addHD( c(1,2,0,0), c(2,-1,0,1))`

This function adds two hyper-dual numbers

`addHD(x, y, verbose = FALSE)`

`addHD(x, y, verbose = FALSE)`

`x` |
A vector of length four containg a hyper-dual number |

`y` |
A vector of length four containg a hyper-dual number |

`verbose` |
A boolean variable with default ‘false’ indicating if verbose operation is desired. |

A vector of length four containing the resulting hyper-dual number.
