pass a system object to a function for codegen

Hi,

I designed a system by using system object in MATLAB. Now I want to generate c codes for a function that uses this system object as input. The function is as follows:

function y = usingSysObj(sysobj, x)  %#codegen
y = sysobj.step(x);
end

in which sysobj is a system object.

when I try to generate code for the function by codegen command I receive an error:

Class Sysobj is not supported by coder.Type.

I would be grateful if someone could help with this problem.

AFAIK, it is not possible to pass in a System object as an argument to a function that you'd like to generate code from. The System object needs to be created inside of the function.
