Generate 2-dimensional normal-distribution

I want to generate 36 observations from a 2-dimensional normal distribution using the covariance matrix

C = [1 0.8;0.8 1];

Anyone know how to do this?

Answer 1

[Matt J]

observations=randn(36,2)*sqrtm(C);

or,

observations=mvnrnd(zeros(36,2),C);

First solution follow the theory from the prevous question. Thanks!!!
