parse error and Directory error for class definition

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
%% %% Define the structure containing all parameters and values
inputData = struct();

Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses.

Hi,

how are you trying to run the code? Clicking the "run" button does not make sense, you need to call the constructor, e.g.

obj = preprocessor()

In a class file, there should generally be no other code. This is why you get the error regarding the inputdata line.

I would avoid having folder names like Car@PC that contain special characters for purpose, such as indicating class folders.

Best wishes,

Harald
