When I try to use semantic-ia-fast-jump, the result is 

"Could not find suitable jump point for *"

if the buffer containing the symbol is not open.  But it will jump to the function if the buffer that contains the symbol is open.  I'm using matlab-cedet.  Admittedly, I am a novice at cedet.  I saw some other posts regarding the same issue, but no answers provided a solution.  I used the latest code from trunk.

Thanks.
