Hello!

I have 6 variables in Simulink. They are:

Car1_Speed, Car2_Speed, Car3_Speed, Car1_ID, Car2_ID, and Car3_ID

I´m comparing the car speeds. I use the max function to find the fastest car at any time. I would like to also know which car is the fastest but I don´t know the way to show also the Carx_ID for the fastest car. Is it possible with Simulink blocks or with some user defined Matlab-function?

How can I do this most efficiently?

Thank you in advance!

Try this (untested):

[maxSpeed, indexOfFastest] = max([Car1_Speed, Car2_Speed, Car3_Speed])
if indexOfFastest == 1
  fastestCarID = Car1_ID;
elseif indexOfFastest == 2
  fastestCarID = Car2_ID;
else
  fastestCarID = Car3_ID;
end
