Hello Bhavik,

The issue mentioned above occurs because a class is not a supported data type for the output port of a 'MATLAB Function' Block. For details on supported data types for the output port, refer to this documentation: https://www.mathworks.com/help/simulink/slref/matlabfunction.html.

Assuming the properties of the 'objectDetection' class are of a data type supported by the 'MATLAB Function' Block output port, try this workaround to resolve the issue:

• Extract the values of the properties from the 'objectDetection' class and store them in a vector.
• Pass this vector as the output of the 'MATLAB Function' Block.

Here is an example code snippet:

function mes = my_func(time, color)
    detection = objectDetection(time, color);
    mes = [detection.Time detection.Color detection.Measurement];
end
