How to use a loop to call function to same plot.

i have a function that draws a random shape but i want to be able to call it 10 times to the same plot so 10 different shapes are drawn around the same point and on the same figure how do I do this?

function plotfunc()
    figure();
 prompt = {'Enter Number of vertices:',}
 numberOfVertices = str2num(cell2mat(inputdlg(prompt, 'enter a number', 5)))
%numberOfVertices = 7; % Fixed at 7 for this demo.
coordinates = rand(numberOfVertices, 2);
coordinates(1,:) = [0, 0]; % Force first coord to 0,0
coordinates(end+1,:) = [0, 0]; % Force last coord to 0,0
hold on;
plot(coordinates(:,1), coordinates(:,2));
 hold on
       plot(coordinates(:,1), -coordinates(:,2));
       hold on
       plot(-coordinates(:,1), coordinates(:,2));
       hold on
       plot(-coordinates(:,1), -coordinates(:,2));
       grid off;
randomColor = rand(1,3);
patch(coordinates(:,1), coordinates(:,2), randomColor); % Can use fill() also.
patch(coordinates(:,1), -coordinates(:,2), randomColor); % Can use fill() also.
patch(-coordinates(:,1), coordinates(:,2), randomColor); % Can use fill() also.
patch(-coordinates(:,1), -coordinates(:,2), randomColor); % Can use fill() also.
axis off;
end
