I am working with MatLab and Simulink. Whenever I run a Simulink model I get an incorrect number of input arguments as the error. my .m file is named makeWhirlyBird. The first function inside the .m file is makeWhirlyBird(u). My interpreted Matlab Function is also makeWhirlyBird(u). and my model is called makeWhirlyBird.mdl. I cannot find a reason for this to happen. Thank You.
