rosenbrock(
f,tSpan,y0,options?):object
Defined in: rosenbrock.js:131
Integrate the stiff system y’ = f(t, y) with an adaptive 4(3) Rosenbrock-Wanner method (Kaps-Rentrop with Shampine’s coefficients).
Parameters
f
Function
(t, y) => dydt; y is Array
tSpan
[number, number]
[t0, tEnd] (tEnd may be < t0 for backward integration)
y0
number | number[]
Initial state
options?
atol?
number
Absolute tolerance
firstStep?
number
Initial step size (auto if omitted)
jac?
Function
(t, y) => nested n x n Jacobian df/dy; central finite differences are used when omitted
maxStep?
number
Maximum step size
maxSteps?
number
Safety cap on accepted+rejected steps
rtol?
number
Relative tolerance
tEval?
number[]
Times at which to report the solution; dense output uses cubic Hermite interpolation between accepted steps
Returns
