Starting another program that shares output terminal with current program?

I have a matlab script that I run from the terminal, that script creates an instance of another program using:
system('cd <path> && mpiexec -n 1 ./<program2> &')
Problem is I don't see any terminal output from program2. (It works if I omit the ampersand, but I need program2 to run in the background). Is it possible to have both the matlab script and program2 output to the same terminal?

Hmm, it's not clear at all what MATLAB does if anything with the output fromsystem('cmd&'); I suspect you'll need to find a different way to solve this problem.

Perhaps you can add>&/dev/ttyto the mpiexec command to make it output to the terminal.

@meuh It didn't work. Still no output in terminal. Output works fine if I direct it to a logfile though...'.... ./<program2> > logfile 2>&1 &'
