Invalid expression error even though the code seems to be correct

this is the code I am trying to run is similar to this

classdef MyParameters
    properties
        param1
        param2
        param3
        param4
        param5
        param6
        param7
        param8
        param9
        param10
        param11
    end
    
    methods
        function obj = MyParameters(params)
            obj.param1 = params(1);
            obj.param2 = params(2);
            obj.param3 = params(3);
            obj.param4 = params(4);
            obj.param5 = params(5);
            obj.param6 = params(6);
            obj.param7 = params(7);
            obj.param8 = params(8);
            obj.param9 = params(9);
            obj.param10 = params(10);
            obj.param11 = params(11);
        end
    end
end

paramsArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11];
myParams = MyParameters(paramsArray);

I keeep getting the following error message

Error using Tail_Design

File: Tail_Design.m Line: 33 Column: 1

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

brackets instead of parentheses.

It highlights the array definition (paramsArray) as the error

It appears you may not understand how to use the code you have shared.

Your classdef code needs to go in it's own m-file (lines 1-31). Save this file with the same name as your class. Then, in a separate script, use the last 2 lines of code you shared to instantiate your class.

paramsArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11];
myParams = MyParameters(paramsArray)

myParams = 
  MyParameters with properties:

     param1: 1
     param2: 2
     param3: 3
     param4: 4
     param5: 5
     param6: 6
     param7: 7
     param8: 8
     param9: 9
    param10: 10
    param11: 11

If you want a quick introduction to OOP in MATLAB, I recommend going through the Object-Oreinted Programming Onramp. It's free, interactive, let's you go at your own pace, and takes about 2 hours to complete.

Understood thanks!
