integration simpson's rule in matlab

To perform numerical integration using Simpson's rule in MATLAB, you can use the integral function with the argument "simpson". Here's an example code:

main.m
% Define the function to be integrated
f = @(x) exp(-x.^2);

% Define the integration limits
a = 0;
b = 1;

% Use Simpson's rule to perform numerical integration
Q = integral(f,a,b,"simpson");

% Display the result
disp(Q);

In this example, the function f is defined as exp(-x.^2), and the integration limits are a = 0 and b = 1. The integral function is then called with the argument "simpson" to use Simpson's rule for the numerical integration. The result is assigned to the variable Q and displayed using the disp function.

You can replace exp(-x.^2) with any other function and adjust the integration limits a and b as needed.
