| 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.
