Hi I'm adapting some code for error checking of blocks in my model.
I would like to know if a block exists inside my model with a certain path and a variable.
e.g
Blockpath='Subsystem/Subsubsytem/Constant' Variable='Value'
What is the quickest way to do this as i would be wanting to do it several times?
Regards
Paul

It depends on the block type, but for a constant block the quick answer is
get_param('Model_Name/Subsystem/Subsubsytem/Constant','Value')
If you aren't sure of the full path, click on the block in simulink, then type gcb in MATLAB. If you want even more capability to search path names and values, look at find_system()
doc find_system
