How can I run a script with admin rights?

What do I have to do, if I try to run a matlab m-script with admin rigths? I would like to get a solution when I haven't started the Matlab with admin rights. Is there a way to start only one single sript with special commands? (user and password)

The management of the privileges depends on the operating system. So it is required to explain, which platform you are using.

You can system() off a new invocation of MATLAB, asking it to run a particular script and quit afterwards. If necessary, have it write graphics to a .fig file and open the .fig file after return.

I do not know the command to request to run as a particular user in MS Windows. In OS-X and Linux, you can "su" or "pseudo" or "ssh"
