(plot),I know how to do the program but the main problem for me in
plot,so this is my program and Graphic shows is not clear,why???
can any one tell me
rand('state',0)
M=input('Enter the number of realization:');
count=0;
X=randn(M,1);
proestimated = zeros(size(X));
for k=1:M
if X(k)>2 count=count+1;
end
end
proestimated = count/M;
disp('estimated probability:')
display(proestimated)
y=@(X)(1/sqrt(2*pi))*exp(-0.5*X.^2); % Anonymous func.
True_probability = quadgk(y,2,inf)
bar(X,True_probability);
hold on
grid on
xlabel('X');
ylabel('True probability');
title('True probability pdf');
bar(X,proestimated);
hold on
grid on
xlabel('X');
ylabel('Estimated probability');
title('Estimated probability pdf');
anybody help me in plot the graph in my program
Thanks in advance

I get a graph, why do you say you don't get a graph? You don't say what to use for the requested input, so I used 10000. Is that wrong? If so, what should we use?

Is there a website or link you can put up which shows the kind of outcome you expect?

The result should show close to such a drawing(not the same but near to such drawing)
