title: Surface Plot of Multivariate Normal Density
body: <p>I have a likelihood function with <a href="https://en.wikipedia.org/wiki/Multivariate_normal_distribution" rel="nofollow noreferrer">Multivariate Normal Density</a> whose mean is <code>mu=[3 5]'</code> and <code>covariance=9*I</code>. How can I plot its 2D surface in Matlab? </p>
