MATLAB: Subfunction with output varargout returns only first element of cell array. Why

Question

This is my script:

 a=9;
 b=2;
 [varargout] = myfunc(a,b)
 c=varargout
 function [varargout] = myfunc(a,b)
 sum=a+b;
 dif=a-b;
 prod=a*b;
 varargout={sum,dif,prod}
 end

After execution, the value of c is 11. I want it to be an array, with values 11, 7, 18. {sum, dif,prod}. What is wrong with my script, and how can I get the desired array?

Answer 1

I you only want all the computations bundled into one output argument, then varargout is not the right thing:

 function c = myfunc(a,b)
   sum=a+b;
   dif=a-b;
   prod=a*b;
   c={sum,dif,prod};
