i am not getting correct output.please help

function [e]=eccentricity(a,b)
if (a||b==0)
    disp('warning');


elseif a<b
        temp=a;
        a=b;
        b=temp;
        e=sqrt(1-(b^2/a^2));
    
else
        e=sqrt(1-(b^2/a^2));
    end
end

e = eccentricity(1,2) % function call

function e = eccentricity(a,b) % function definition , a & b assumed as scalars for this task
if any(ismember([a,b],0))
    e = sprintf('warning');
elseif a < b
    temp = a;
    a = b;
    b = temp;
    e = sqrt(1-(b^2/a^2));
else
    e = sqrt(1-(b^2/a^2));
end
end
