About S -function errors ,How can I solve the problems?
Show older comments
when I writed codes in S-function and runed in matlab, I got two errors: (1)Error in 'hy_test_onlinelearning/S-Function' while executing MATLAB S-function 'hy_onlinelearning', flag = 2 (update), at time 0.0. (2)Too many input arguments. How can I solve these problems ? Thank you very much.
The codes are below: function [sys,x0,str,ts,simStateCompliance] =hy_onlinelearning(t,x,u,flag,G,I) switch flag,

Only 3 arguments are passed to the mdlUpdate stage, so you need to define your function prototype as:
sys=mdlUpdate(t,x,u);
Please also look at the example models if you are getting started with S-functions. Run "sfundemos" and navigate to 'MATLAB file S-functions>Level-1 MATLAB file S-functions'. Note that Level-1 MATLAB S-functions have been deprecated for several releases now, so if you're writing a new S-function, we highly recommend writing it as a Level-2 MATLAB S-function.

autshy: We highly discourage sending personal messages. I would really prefer continuing the conversation here so others who face a similar problem in the future may benefit from it. Please only paste the two parts of your S-function code where mdlUpdate is called and where it is defined. Also, if the error message is now different, please paste that as well.

Have you also updated the switch-case statement?
case 2,
sys=mdlUpdate(t,x,u);
