MATLAB sessions: Laboratory 3 MAT 275 Laboratory 3 Numerical Solutions by Euler and Improved Euler Methods (scalar equations) In this session we look at basic numerical methods to help us understand the fundamentals of numerical approximations. 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.…
