you're encountering errors when trying to set an object property type to an abstract class "matlab.mixin.Heterogeneous" in MATLAB. The matlab.mixin.Heterogeneous class is used to enable heterogeneous arrays in MATLAB, which means you can have arrays containing objects of different classes that inherit from the same base class.

However, without the specific error message you're encountering, it's a bit difficult to provide a precise solution. Nonetheless, I can give you some general advice on how to approach this issue:

1. Check Inheritance: Ensure that the class you're trying to use as a property type inherits from matlab.mixin.Heterogeneous. If the class does not inherit from this abstract class, you will not be able to set it as the property type.

2. Syntax and Typing: Make sure you're using the correct syntax for setting a property type. Here's an example of how you might do it:

properties
    MyProperty (matlab.mixin.Heterogeneous)
end

1. Error Message Analysis: Carefully analyze the error message you're receiving. It might provide you with valuable information about what exactly is causing the issue.

2. Namespace: Verify that you are correctly referencing the matlab.mixin.Heterogeneous class and it's in the expected namespace. The correct namespace might be different depending on your MATLAB version.

3. MATLAB Version Compatibility: Ensure that the matlab.mixin.Heterogeneous class is available and supported in your MATLAB version. If you're using an older version, it's possible that the class might not exist.
