I am using the WaterTank Matlab example code and adapting it to my own specific problem. I'm getting an error that "WaterTank.slx" is not a valid MATLAB function. Sorry, I don't understand what the problem is.
My working folder is WaterTank, and contains files WaterTank.mlx and WaterTank.slx. At line 65 I am trying to select the variant 'ADRC' and get the error.
