<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). Large objects (like bitmap images) could also be passed by using external files (i.e. only passing the name of the created file).<br>

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>
