It works, but it's ugly :-)

Never realized that MATLAB sees a defined assignment (y = 2*x) different than no assignment (2*x => assignment to ans).
If anything, I would have guessed the second would be (slightly) more effort.

does this variable "ans" overrides MATLAB's default "ans"?

David Amor on 27 Apr 2013

ok, i got there in the end. but it defeats the rules - there is no "y" variable when you change the template to ans = times2(x)...

how do you know what the rules are?!?

David Amor, the rules specify that you have to assign it to a "y" variable. You just need to do
y = times2(x);

Hi Dirk, can you pls tell me how you got size 10 ?

Beniamin Stecula on 11 May 2022

To get size 10 you have to change y to ans:
function ans = times2(x)
2*x;
end
