matlab simulink supported data types

Hi all...how can I test datatype of a matlab function? ...for example ,I want to know the datatype of the function adaptfilt.lms because I have an error about specifying the datatype of the called function to matlab function block.

class() will show you the data type for its argument.

adaptfilt.lms returns a "FIR LMS object" according to the documentation. The datatype involved will not be one of the fundamental arithmetic data types such as "double", and it will not be a cell array or a struct: it will be an Object Oriented Programming (OOP) object.

I do not know if you are permitted to pass such objects to a MATLAB Function Block (that is, this is outside my experience.)

You can only use the adaptfilt.lms function in your MATLAB Function block, but not use it as input/output.
