xpc parameter passing and recording

    Dear All,

I have 2 questions on xPC... they might be really simple, but I would really appreciate some help. 

 1) can I pass parameters to my model on xPC, before starting it? This way, I would not have to loose time by re-compiling the model each single time. E.g. let's say I want to run the same model twice, once with a = 2 and once with a = 6 , without recompiling. 

 2) can I record a parameter of my running model at ONLY one time-point of the run? Something like "record the value of this output only at time t". 

Thanks a lot for any help.

1. See the xPC documentation on Parameter Tuning to see how you can modify parameters without re-compiling.
2. I believe you should be able to use an xPC Target Scope block and trigger it at a specific time and for a specific number of samples. I don't have any experience doing this, but there is some documentation here: http://www.mathworks.com/help/toolbox/xpc/gs/f0-35834.html#f0-61032

Thanks a lot! tg.setparam(..) is the key.
