Euler-Maruyama method For ODEs, the forward Euler method has O(h) accuracy, and other more accurate methods would usually be preferred. However, SDEs are very much harder to approximate so the Euler-Maruyama method is used widely in practice. Numerical analysis is also very difficult and even the definition of “accuracy” is tricky.The ode14x solver uses a combination of Newton's method and extrapolation from the current value to compute the model state as an implicit function of the state and the state derivative at the next time step. In this example, X is the state, dX is the state derivative, and h is the step size: X(n+1) - X(n)- h dX(n+1) = 0. Euler Method Setting h Value.
