Hi!
when I run the following code: n = 1000; rho = .7; Z = mvnrnd([0 0], [1 rho; rho 1], n); U = normcdf(Z); X = [gaminv(U(:,1),2,1) tinv(U(:,2),5)];
I get the following error:
??? Undefined function or method 'mvnrnd' for input arguments of type 'double'.
Error in ==> U3 at 3 Z = mvnrnd([0 0], [1 rho; rho 1], n);
seems like I don't have the function. When I do "exist mvnrnd" I get ans = 0.
I am using a 2005 version with the R2011a update. Do I have to installs all updates CDs I have form 2005 to 2011?
Thanks a lot.

The function mvnrnd is part of the statistics toolbox. Firstly, in order to use this function you have to have the Statistics Toolbox installed. This can be confirmed using the command:
ver
Secondly, you need to have a license for the Statistics Toolbox, this can be confirmed using the command:
license('test','Statistics_Toolbox')
