The code gets executed when entering the "Modes" state and every simulation step while the Modes state is active. To understand the "<" sign, type the code into the MATLAB command window:

>> SonarSensors = [1 1 1 1 1];

>> SensorRanges = [2 2 2 2 2];

>> [SonarSensors(4:5)] < SensorRanges(4:5)

ans =

1×2 logical array
