how can we plot the data that we get from a for loop, just by joining the end points? I mean to say how can we form a closed figure? below is the code that i have done.

%Asks the user, the number of vertices in their polygon fprintf('Enter The Number of vertices in your polygon\n'); n = input('n: ');

if n<3 %Check if the number of vertices is less than three or not fprintf('Wrong input, Please enter value greater than 2,Further calculation not possible exitting....'); exit(); end

%Asks the user for the coordinates of the vertices

fprintf('Enter The Coordinates of the polygon\n'); vertices=[];

for i = 1:n x = input('Enter the coordinate of x axis'); y = input('Enter the coordinate of y axis'); vertices=[vertices;x y]; end

%Prints the coordinates of the vertices fprintf('The coordinates you enter are\n'); vertices

Add the first point at the end so it becomes closed. After the loop:

Vxy = [vertices ; vertices(1,:)] 
plot(Vxy(:,1), Vxy(:,2),'-')

Thanks. It works!!
