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)

Ran in:
% 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')
