The code creates 10 random ellipses
N = 10;
for R = 1:N %for loop to repeat 10 times
t = linspace(0,2*pi); % t defined angle??? not sure
xc = randn; %defines one of axis as random
x = xc + randn*cos(t);
yc = randn;
y = yc + randn*sin(t);
plot(x,y)
patch(x,y,rand)
hold on %puts all ellipses on same graph
end
How do I add to the code to make it so that everytime i run this code i get the same graph with the same random numbers inputed?
