hey guys, in the below code, i am having 2 errors:

I cannot run the code due to this error: "A class definition must be in an "@" directory",
there is a "parse error usage might be invalid matlab syntax" at line "inputData"
the working folder in this case is : C:\Users\auto\Car@PC\Templates\@preprocessor
inside templates folder I have also other working .m scripts, but without any class definitions.
matlab verison R2015b

How to solve this issues?

Thankyou!

classdef preprocessor
   
    
    properties
        vehicleParameters
        weatherConditions 
        roadDefinitions
        maneuvers
        faultInjections
    end
    
    methods
        function obj = preprocessor(vehicleParams, weatherConds, roadDefs, maneuvers, faults)
            if nargin > 0
                obj.vehicleParameters = vehicleParams;
                obj.weatherConditions = weatherConds;
                obj.roadDefinitions = roadDefs;
                obj.maneuvers = maneuvers;
                obj.faultInjections = faults;
                
            end
    end
    
    end
end
