How to generate $n$ samples from a $d$-dimensional multivariate Gaussian distribution with a given covariance matrix $\boldsymbol \Sigma$? This is easy to do by generating samples from a standard Gaussian and multiplying them by a square root of the covariance matrix, e.g. by $\mathrm{chol}(\boldsymbol \Sigma)$.
