The question is toWrite a MATLAB script to do the following a. Create 10000 random variables uniformly distributed between 2 and 4. b. Create a histogram to approximate the actual probability density function. c. Superimpose the actual probability density function to the above histogram
This is what I have gotten so far
a=2; b=4; n=10000; r = a + (b-a).*rand(n,1);
xlabel('index');ylabel('Amplitude');grid pause X=1:10 y = unifpdf(X,2,4); hist(r,10) got stocked
Thank you so much

a=2; b=4; n=10000; r = a + (b-a).*rand(n,1);
xlabel('index');
ylabel('Amplitude');
grid
%pause
X=1:10;
y = unifpdf(X,2,4);
[nh,xout]=hist(r,10);
hold on
plot(X,y,'r')
bar(xout,nh/n)
legend('unifpdf','hist')
