Problems with adding block from target link into a model

Hi
I’m trying to add a block from the library TargetLink with the command: "add_block('tllib/Constant','mysys/nameofconstant','Position',[]).
But Matlab answers with:"??? Error using ==> add_block There is no block named 'tllib/Constant'.".
But if there already exist a model in the same folder containing a TargetLink block, then Matlab has no problem executing the command.
Do anyone have a idea how to fix this problem or how to make a work around.

You maybe need to load the library before using add_block:
load_system('tllib');
add_block('tllib/Constant','mysys/nameofconstant','Position',[]);
HTH,

Yep, this happens. What you need to do is to make sure that 'tllib' is loaded first. You can use load_system('tllib');
