function quadrature to find area under curve in matlab

To find the area under a curve in MATLAB, you can use the quadrature function. The quadrature function calculates the definite integral of a function between two limits. In this case, we want to integrate the function representing the curve and calculate the area under it. Here's an example code snippet:

main.m
% Define the function representing the curve
f = @(x) x.^2;

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

% Use the quadrature function to calculate the area under the curve
area = quadrature(f, a, b);

% Display the calculated area
disp(['The area under the curve is ', num2str(area)]);

In this example, the curve is represented by the function f(x) = x^2. The limits of integration are a = 0 and b = 1. The quadrature function is used to calculate the area under the curve, which is then displayed to the console.

Note that you can replace the f function in this example with any function that represents the curve you want to find the area under.
