Multiple-Application Trapezoidal Rule
Implementation based on the theory presented in "Numerical Methods for Engineers" by Steven C. Chapra
Instructions to use the function:
The user must provide the function as an anonymous function in the command window. This can be done by introducing
Then, the user should invoke the function by indicating four parameters:
where f is the integrand and N is the number of intervals. lmin and lmax are the lower and upper limits of the definitive integrand. In addition, a figure is depicted showing the evaluation points and an approximated integration region.
