Create function that varies between 1 and zero if input is 1 or 2

Hello as the title explains I want to create a function that gives an output of either 1 or zero depending if the input is 1 or 2 this is what I've tried but does't seem to work:

function [y1,y2] = delt(x)

if x == 2
     y1=1;
else 
    y2=0;
end
end

The output variable should be the same -

y1 = delt(1)

y1 = 0

y2 = delt(2)

y2 = 1

y3 = delt(-69)

y3 = 0

function y = delt(x)

if x == 2
    y=1;
else 
    y=0;
end
end
