histogram for gaussian distribution.

Generate an array of length N where each array element is a sample from a Gaussian

distribution with mean 0 and variance 1. Use the Matlab command histogram to plot

the histogram of these numbers. Vary N = 50, 100, 2000 to observe the difference

in the histogram. Change the variance to 0.25, 2, 5 for N = 2000 and observe the

difference in the histogram.

i have made the code but it is wrong.

N = input("value : ")

data = randn(N);

a = 1;% standard deviation

b = 0; % mean

out = a.*data + b;

hist(out)

% N = input("value : ")
N = 2000;
data = randn(N, 1);   % randn(N) => NxN
a = 1;%  standard deviation
b = 0; %  mean
out = a.*data + b;
histogram(out, 'Normalization', 'pdf')
