DormandPrince.jl
Julia-native implementation of the Dormand-Prince 5th and 8th order solvers
Installation
DormandPrince is a
julia
pkg> add DormandPrince
Usage
Single End-Time
```julia julia> using DormandPrince
define your ODE, in this case, dy/dx = 0.85y
julia> function fcn(x, y, f) f[1] = 0.85y[1] end
Create a solver object. We will use the 5th order solver and
start integrating at t = 0.0 with initial value of 19.0
julia> solver = DP5Solver(fcn, 0.0, [19.0])
Begin integration up to t = 2.1
julia> integrate!(solver, 2.1)
getcurrentstate will return the answer
julia> getcurrentstate(solver) ```
Both the DP5Solver and DP8Solver's are stateful allowing for memory-efficient integration to future end times from the last integrated end point (e.g. if you chose t = 1.0 as your endpoint you can call integrate! again with t=2.0 and it will "carry forward" the work starting from t = 1.0 instead of requiring you to set things up all over again).
Multiple End-Times
```julia julia> using DormandPrince
Define ODE
julia> function fcn(x, y, f) f[1] = 0.85y[1] end
Define times of interest to analyze/perform actions on the solution
julia> times = [1.0, 1.1, 1.9, 2.4]
Create the solver object, with integration starting from t = 0.0 and initial value of 19.0
julia> solver = DP5Solver(fcn, 0.0, [19.0])
Empty array to store intermediate values
julia> intermediate_values = []
Use callback to store intermediate values. The solver object will also be mutated to store the solution
found at the last time point.
julia> integrate!(solver, times) do time, val push!(intermediate_values, val[]) end
```
You may also create a SolverIterator that can then be iterated over. Note that this will require a fresh solver
julia
for (time, value) in SolverIterator(solver, times)
println("Time: ", time, " ", "Value: ", value[])
end
