Problem in drawing

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 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?

also,I get a graph but I think the result of graph is not true,if I

enter 100 or 10000,the number of realization is not problem for me

but I expect that the drawing is incorrect

Because it is not systematic

I want to use the plot, hist for drawing my program not bar command

But there is no any result when I used the (plot and hist command)at

the same time

this is my problem here!

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

[reem]

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