write a code to find the integral of function in matlab

To find the integral of a function in MATLAB, you can use the integral function which allows you to compute definite integrals numerically.

Here is an example code to find the integral of a function f(x) from a to b:

main.m
% Define the function f(x)
f = @(x) x.^2 + 3*x + 5;

% Define the integration limits
a = 0;
b = 5;

% Compute the integral
integralValue = integral(f, a, b);

% Display the result
disp(['The integral of the function from ' num2str(a) ' to ' num2str(b) ' is: ' num2str(integralValue)]);

In this code snippet, we define a function f(x) using an anonymous function, specify the integration limits a and b, then use the integral function to compute the integral of f(x) over the interval [a, b]. Finally, we display the result.

You can modify the function f(x), and the integration limits a and b as per your requirements.
