plot of theta_new and cos theta

clc
clear
format compact
nmc = 1000
theta_initial = 0
% b = ones(2)
for i = 1:nmc
a = round (rand(1)-0.3)

theta_new = a + theta_initial
if theta_new(1,1) > theta_initial(1,1)
    theta_initial = theta_new
    plot(theta_new,cos(theta_new),'*')
if theta_initial >= 90
    break
end
end

end
 plot(theta_new,cos(theta_new),'*')

how i can correct for plotting theta_new and its cos(theta_new)

[Walter Roberson]

After the first

    plot(theta_new,cos(theta_new),'*')

add

   hold on

and remove the second plot() call.
