<br></div>There are a few functions available to pass variables, character array's, matrices and workspaces between the two applications, without the need to convert strings. The execute command should be used to execute scripts; not for passing variables (although you can do this off course).

Hi,<br>
Never heard of a way to interface matlab from E-Prime, I'd be interested if anyone would have a way. Of course, you could compile from within matlab and try to go from there, but I suspect the amount of effort would really not be worth it. You could, of course, just forego e-prime and try Psychtoolbox.<br>

Subject: Re: Polhemus<br>
<br>
To be more precisely: What I need to do is to start a matlab script from E-Prime.<br>
"Presentation" has some plugin to connect with Matlab, but E-Prime seems not to have that. But there may be another way...<br>

Does anyone have experience with running Polhemus Liberty (the motion tracking system) with E-Prime?<br>
