Using Matlab classes in Grader

I would like to use a Matlab class in Grader. The students should define a class myclass which is also implemented in the reference solution. According to the Matlab help,I use function based assessments:

%Student solution
y = myclass([1 2 3], 1)


% Run reference solution.
yReference = reference.myclass([1 2 3], 1) 

% Compare.
assessVariableEqual('y', yReference);

The Pretest results say:

Variable y must be of data type reference.myclass. It is currently of type myclass. Check where the variable is assigned a value.

How should I solve this?

Thank you in advance!

In my opinion, classes go a bit beyond what MATLAB Grader was designed for. Still, it is possible to create and use classes in a function-type problem in a somewhat limited manner. However, the assessVariableEqual function cannot be used to assess a class object directly.

Assessments that work

• Check for the presence of methods by name
• use the methods and ismethod functions to query all public, non constructor and non set/get methods.
• Use the properties function to determine what public properties the class contains.
• Use dot notation to access the value of public properties.
• assessVariableEqual can compare values
