SUMMARY

The discussion focuses on integrating expressions in MATLAB, specifically addressing difficulties encountered with the integration functions. The user attempted to use the obsolete

quad

function and the

romberg

method but did not achieve the desired results. It was suggested that the

ode23

function could be a viable alternative, although the user struggled with its implementation. Additionally, it was noted that the

integral

function should be used instead of

quad

for better results.

PREREQUISITES

  • Familiarity with MATLAB programming
  • Understanding of numerical integration techniques
  • Knowledge of the

    ode23

    function for solving differential equations
  • Experience with the

    integral

    function in MATLAB for numerical integration

NEXT STEPS

  • Learn how to implement the

    integral

    function in MATLAB for numerical integration
  • Explore the usage of the

    ode23

    function for solving ordinary differential equations
  • Research the differences between

    quad

    and

    integral

    functions in MATLAB
  • Investigate common errors in MATLAB integration and their solutions

USEFUL FOR

MATLAB users, engineers, and researchers involved in numerical analysis and integration tasks who require effective methods for computing integrals in their projects.

hell, i have been trying to compute the integral of an expression in matlab, but when it comes to the integration part i can't get the right result. i tried the quad function, and one named romberg i found online. I have been told the ode23 function could work, but i can't figure out how to use it.

I've already created the function in MATLAB and tested it for some values, and they are correct, but when it comes to the integration part i can't get it right.

does anyone have some ideas on what can i do?

thanks
