pdf for jointly gaussian
http://www.mathworks.com/matlabcentral/newsreader/view_thread/294674#790259
Ronald Yu
I am a new user to matlab,<br>
I am trying to show pdf for two jointly gaussian.<br>
If both random variables have zero means, and ρ = 0.8, σ1 = 1, σ2 = 10.<br>
how should i write this program?

It is not clear what program you wish to write. What do you want to accomplish? At the website<br>
<br>
<a href="http://en.wikipedia.org/wiki/Multivariate_normal_distribution">http://en.wikipedia.org/wiki/Multivariate_normal_distribution</a><br>
<br>
there is a specific formula given for the twovariable density function you are asking about. Are you trying to plot the distribution using 'surf'?<br>
