Check or translate between deSolve and Julia DifferentialEquations solvers

solvers.Rd

This function either checks whether a solver method exists or provides bidirectional translation between R's deSolve package solvers and Julia's DifferentialEquations.jl solvers.

Usage

solvers(method, from = c("R", "Julia"), to = NULL, show_info = FALSE)

Arguments

method

Character string of solver name

from

Character string indicating source language: "R" or "Julia"

to

Character string indicating target language: "R" or "Julia"

show_info

Logical, whether to display additional solver information

Value

Character vector of equivalent solver(s) or list with details
