I have a signal of a switch with ON/OFF situation. How can I get how many times it actuates by matlab, simulink, or script?

When the value is not equal to previous value, the counter should be increased by 1. I want total count in a certain time period.

sum(diff(YourSignal) ~= 0)

Can You please tell me how do I put this script in matlab function simulink block to get total number of actuation's as output?

Maybe something like this:

loopCounter = 0;
count = 0;
oldSwitchReading = -1;
stillCheckingSwitch = true;
while stillCheckingSwitch && loopCounter < 1000000
   thisSwitchReading = % Some code to read your switch.....
   if thisSwitchReading  ~= oldSwitchReading 
        count = count + 1;
   end
   oldSwitchReading = thisSwitchReading; % New/current state is now the old state for the next iteration.
   loopCounter = loopCounter + 1; % Increment fail-safe.
   % Decide if we need to quit checking the switch
   stillCheckingSwitch = % Code to determine when to quit.....
end
