Students can create a large number of random points within the integration domain using MATLAB's random number generation capabilities, and then use those points to estimate the integral. Students may be required to complete exercises in which they use Monte Carlo integration to approximate definite integrals, analyze the rate of convergence as the number of samples rises, and investigate various sampling techniques, including stratified sampling and importance sampling. Students can also evaluate error estimation methods like the Central Limit Theorem to measure the precision of Monte Carlo integration. Students will gain practical experience with Monte Carlo integration through this assignment and deepen their understanding of its probabilistic nature used in resolving challenging integration problems.

  9. Romberg Integration
  10. Romberg integration is an iterative technique for numerical integration that boosts precision by combining Richardson extrapolation and the trapezoidal rule. The Romberg integration algorithm can be implemented, the convergence process can be understood, and the error reduction with each iteration can be examined by students as they work on a MATLAB assignment. Students will comprehend Richardson extrapolation and its role in improving the accuracy of numerical integration more fully by applying the Romberg integration algorithm in MATLAB. Exercises, where students use Romberg integration to approximate the definite integrals of various functions and examine how convergence changes as the number of iterations rises, can be a part of the assignment. Students will see how the Romberg integration algorithm converges to the exact solution by improving the approximation with each iteration. They can contrast Romberg integration with other numerical integration techniques in order to investigate the trade-off between computational complexity and accuracy. The iterative nature of Romberg integration and its practical applications in achieving highly accurate integration results will be explained to students in-depth through this assignment.
