confused graph,probability

After greeting and respect

Every time when I want to do my program,everything is stop in graph

(plot),I know how to do the program but the main problem for me in

plot,so this is my program and I have problem in plot(graph)

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

What do you typically enter for number of realization?

100

you can enter any number
