Hi. I have a program (lots of functions) which creates an interface and I want to add a dialogue box saying "a router was found" every time the signal level reaches a certain threshold. Also, the signal value is retrieved in real time. My other question is : can I simulate a signal so that I can test the newly added "a router was found" dialogue box.
I attach my code in the hope that anyone can help and apologize that it's in romanian. The graph reads : "power spectral density", and the others are "energy detection parameters" and "data acquisition parameters".

Tiberius - consider using a msgbox such as
msgbox('A router was found','Information')
whenever a signal reaches a certain threshold. (This will be a non-modal dialog; see the link for more details.)
You've only attached the m-file, so we can't run trough the GUI (would need the fig file for that) but you should be able to determine where in the code to add the message box logic.
