And what about subroutine myroot on page 17 of this vignette? -----Original Message----- From: R-sig-dynamic-models [mailto:r-sig-dynamic-models-bounces at r-project.org] On Behalf Of Derek van der Kamp Sent: dinsdag 24 maart 2015 0:58 To: r-sig-dynamic-models at r-project.org Subject: [R-sig-dyn-mod] root functions in fortran Greetings, I was wondering if anyone has experience writing root functions using fortran I would like to keep one of my state variables below a certain value. To do this I want to use a root function to determine when that theshold value is reached, and an event function to keep the state variable below that threshold. However, I'm using fortran, and I can not find any examples in which a root function was used in compiled code. In the package vignette ( http://cran.r-project.org/web/packages/deSolve/vignettes/compiledCode.pdf) no root function is ever used; the event function is called based on pre-defined event times. Is it possible to define and use a root function in fortran? Thanks for your time, Derek van der Kamp _______________________________________________ R-sig-dynamic-models mailing list R-sig-dynamic-models at r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-dynamic-models
