So this doesn't work if either of the t = 0:0.2:2 OR t = linspace(0,2,100); are commented or not.
How do I get it to work since the turorial sheet says that this exact code should work if I run:
[a,b,c] = ThreeFunc2(i1,i2,i3)
But it doesnt.
It gives the error:
Unrecognized function or variable 'i1'.

The variables i1, i2, and i3 in the function call
[a,b,c] = ThreeFunc2(i1,i2,i3)
or the variables t, f1 and f2 in the function call
[a,b,c] = ThreeFunc2(t,f1,f2)
need to be defined before the function call, not just exist within the function. Those variables are expected as inputs.

Your assignment explicitly states, "the time vector you specified in parameter i1", in other words you need to tell your function what i1 is.
The assignment is admittedly less clear on what to do with i2 and i3 (although it does say you can use a number for i3).

Riiight, that makes a lot of sense.
Thanks for your time,
sorry for being slow.

I think you can do something like this:
t = 0:0.01:10;
f1 = 1/10;
f2 = 1/5;
% Call the function
ThreeFunc2(t, f1, f2)
% Write the tasks to be carried function
function ThreeFunc2(t, f1, f2)
y1 = sin(2*f1*pi*t);
y2 = cos(2*f2*pi*t);
plot(t, [y1' y2']), grid on
end
