MATLAB: Random generation and ploting its pdf

pdf

i want generate number from 0 to 100 and plot its pdf(probability density function) as well as mean ,standard deviation.
Thank you.

n=randi(101,1000,1)-1;
hist(n,101)
m=mean(n),s=std(n)

2 + 8*randn(1, 100) + 4*randn(100,1);

or in more detail

n = 1; m = 100; % number of samples
m1 = 2; s1 = 8; s2 = 4;
m2 = m1 + s1*rand(n, m);
X = m2 + s2*rand(n, m);

a = .3;%  standard deviation
b = 0; %  mean
out = a.*randn + b;
