Creating a vector randn

Hi,

I would like to know how to create a 1x301 vector that has Gaussian distribution with 0 mean and some variance sigma. Thanks in advance!

Hi,

This page helps you to solve this.

https://www.mathworks.com/help/matlab/math/random-numbers-with-specific-mean-and-variance.html?s_tid=answers_rc2-3_p6_Topic

As stated in the page

y = sqrt(variance).*randn(1,301) + mean;
% As mean is 0, variance is sigma
sigma = 5;
mean = 0;
y = sqrt(sigma).*randn(1,301) + mean;

Hope this helps.

Regards,

Sriram
