how to calculate the area of a polygon in matlab

To calculate the area of a polygon in MATLAB, you can use the "polyarea" function. This function takes the x and y coordinates of the vertices of the polygon as inputs and returns the area of the polygon.

Here's an example of how to use the "polyarea" function:

main.m
% Define the coordinates of the vertices of the polygon
x = [0 1 1 0];
y = [0 0 1 1];

% Calculate the area of the polygon
area = polyarea(x, y);

% Display the area
disp(['The area of the polygon is ', num2str(area)])

In this example, the polygon has four vertices located at (0,0), (1,0), (1,1), and (0,1). The "polyarea" function calculates the area of the polygon and stores it in the variable "area". Finally, the computed area is displayed to the user.
