I have a simple simulink model,
  1. two states - On and OFF
  2. one output - y, attached to a scope
  3. one parameter - u
  4. transition rules - when u < 0 goto OFF, when u > 0 go to ON
I'm trying to do the following from the workspace,
set_param ('Model/Block','u','1')
and I'm getting 'subsystem block does not have a parameter named 'u''...all I want to do is to toggle the parameter 'u' from 0 to 1 and 1 to 0 to observe the effect on the scope..
Can someone plz point out where I have gone wrong?
Many thanks, Luke

Can you be more clear about what kind of parameter 'u' is? Is it a constant block? A mask parameter? A parameter in the model workspace?
Try
get_param('Model/Block', 'ObjectParameters')
to see what you are allowed to set.
