how to plot user defined pdf

this is my program:

n = input('enter the value of a ');

z=n-1;

e= exp(1);

y = ((sqrt(2*pi*z))*((z/e)^z));

display(y);

b= input ('enter the value of b');

for x=1:100

    p= ((x^z) * (e^(-(x/b))))/(y*(b^n));
    plot(x,p);
    drawnow
end

please correct it

Please read the instructions found at "About MATLAB Answers" to learn how to format your code and how to ask a good questions. Thanks.

When you ask for a correction, it would be a good idea to explain the problem. Do you get an error message or do the results differ from your expectations?

Well one problem you have is that you don't define i anywhere. Since i by default is the unit imaginary, you should probably use another variable.

Why are you using a loop, I think better to do something like

z = 9;
b = 2;
e= exp(1);
x = 1:100;
p  = ((x.^z).* (e.^(-(x/b))))./(y*(b.^n));
plot(x,p)

Doing it the way you are in a loop, you are just plotting a single point in the plane.

Now that you've edited your original post to fix your variable problem, my first comment does not apply, but what about the solution I gave you? Do you really need a loop?

thank you bro, It worked
