What is wrong with my arrayFun function ?

Dear all, I have an arrayFun function. This function totally runs well when I use array ( CPU Array ) . The problem appears when I was trying to assign gpuArray ( similar array to the one in CPU, but I assign it to GPU ) into this arrayFun function. There is message appears in my command window "Package functions and MCOS class methods are unsupported" Does anyone have any idea what's wrong with my code ?

Thanks a lot !

P.s. When I tried another arrayFun function using gpuArray input, it is totally OK

It would be really helpful if you showed the actual code that is causing an error, rather than trying to guess it.

Not all functions are overloaded for GPU arrays. Is the function you are using actually applicable to a gpuArray even without the arrayfun?

The error message is trying to indicate to you that the body of your arrayfun function cannot contain either method calls on MATLAB objects, nor can it contain calls to package functions (i.e. function names containing a . character).
