Currently the serial version of ODE solver, 'CVODE', sensitivity calculator 'CVODES' and differential algebraic solver 'IDA' from the 'SUNDIALS' library are implemented. The package requires ODE to be written as an 'R' or 'Rcpp' function and does not require the 'SUNDIALS' library to be installed on the local machine.https://github.com/r-universe/sn248/actions/runs/39102912183Sun, 18 Oct 2026 03:39:27 GMTsundialr0.2.1successhttps://sn248.r-universe.devhttps://github.com/sn248/sundialrmy-vignette.Rmdmy-vignette.htmlsundialr - An Interface to 'SUNDIALS' Ordinary Differential Equation (ODE) Solvers2018-04-02 16:20:062026-10-18 03:21:40satyaprakash.nayak@gmail.com (Satyaprakash Nayak)Provides an interface from R to the 'autodiff' library <https://autodiff.github.io/>, a modern header-only C++ library for automatic differentiation. Unlike numerical differentiation, automatic differentiation computes derivatives of functions to machine precision without truncation error, using either forward or reverse mode. The 'autodiff' header files are shipped with this package so that other R packages can use them by including 'Rcppautodiff' in the 'LinkingTo' field of their 'DESCRIPTION' file. Example programs demonstrate computing derivatives of single-variable and multi-variable functions, gradient vectors, Jacobian matrices and derivatives with respect to parameters, using 'Rcpp' and 'RcppEigen'.https://github.com/r-universe/sn248/actions/runs/36831936781Sun, 02 Aug 2026 01:14:13 GMTRcppautodiff0.1.0successhttps://sn248.r-universe.devhttps://github.com/sn248/rcppautodiffIntroduction-to-Rcppautodiff.RmdIntroduction-to-Rcppautodiff.htmlIntroduction to Rcppautodiff2022-07-11 14:14:072026-07-09 00:58:37
