I'm trying to execute this function in matlab/simulink but the following errors are cropping up:
  1. The 'timer' class does not support code generation.
  2. Undefined function or variable 'start'.
  3. Function 'delete' is not supported for code generation.
I want this program to wait for some time(say 15 sec) after step 1, then execute step 2 and wait again, similarly wait after executing step 3.
function y = fcn(v1, v2, v3, v4)
ar=[v1,v2,v3,v4];
%step1
[~,I]=max(ar);
y=I+1;
t = timer('TimerFcn', 'disp(''wait'')','StartDelay',15);
start t;
delete t;
%step2
y = 1;
t = timer('TimerFcn', 'disp(''wait'')','StartDelay',15);
start t;
delete t;
%step3
[~,I1]=min(ar);
y=I1+1;
t = timer('TimerFcn', 'disp(''wait'')','StartDelay',15);
start t;
delete t;

You would have to turn off all accleration, in order to turn off code generation.
However, you are using very much the wrong approach.
