problem in drawing my small program

After greetings and respect

please,anyone tell me about my problem here

when I want to plot using plot command,nothing appear in my

graph,why??

Thanks in advance

clear all;

randn('state',0)

M=input('Enter the number of realization:');

counter=0;

X=randn(M,1);

for k=1:M

   if X(k)>2

   counter=counter+1;

   end

end

proestimated = counter/M;

disp('estimated probability:')

display(proestimated)

plot([-4:1:4],proestimated);

Answer 1

[Walter Roberson]

proestimated will be a single scalar. The plot documentation does say,

If Xn is a scalar and Yn is a vector, plots discrete Yn points vertically at Xn.

but it does not include the reverse case, where Yn is a scalar and Xn is a vector.

You will need to make the size of the Y value to be plotted the same as your X value to be plotted.
