time (s)\ndt = 0.1  # time step (s)\nz = RD.KnotPoint(x,u,t,dt)\n\n# Evaluate the continuous dynamics and Jacobian\nẋ = dynamics(model, x, u)\n∇f = zeros(n, n + m)\nRD.jacobian!(RD.StaticReturn(), RD.ForwardAD(), model, ∇f, ẋ, model, z)\n\n# Evaluate the discrete dynamics and Jacobian\ndmodel = RD.DiscretizedDynamics{RD.RK4}(model)\nx′ = RD.discrete_dynamics(dmodel, model, x, u, t, dt)\nRD.discrete_jacobian!(RD.StaticReturn(), RD.ForwardAD(), dmodel, ∇f, x′, z)\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Froboticexplorationlab%2Frobotzoo.jl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Froboticexplorationlab%2Frobotzoo.jl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Froboticexplorationlab%2Frobotzoo.jl/lists"}
