# MATLAB: How does the following two codes differ? both are working, but they are yielding different answers

Hello,
Could you explain for me why I'm not getting the same answer from the following two codes??
function whatswrong(x)x1= linspace(0,x);n=length(x1);    uy = -5/6.*(sing2(x1,0,4)-sing2(x1,5,4))...        + 15/6.*sing2(x1,8,3) + 75*sing2(x1,7,2)...        + 57/6.*x1^3 - 238.25.*x1;plot(x1,uy,'--')xlabel('x1')     ylabel('uy'),     title('displacement versus distance')function check = sing2(x1,a,n)    if x1 > a        check = (x1 - a).^n;    else        check=0;    end
——————————————————————————————————
function beam2(x)x1= linspace(0,x);n=length(x1);for i=1:n    uy(i) = -5/6.*(sing(x1(i),0,4)-sing(x1(i),5,4));    uy(i) = uy(i) + 15/6.*sing(x1(i),8,3) + 75*sing(x1(i),7,2);    uy(i) = uy(i) + 57/6.*x1(i)^3 - 238.25.*x1(i);endplot(x1,uy)    function check = sing(x1,a,n)    if x1 > a        check = (x1 - a).^n;    else        check=0;    end
many many thanks,
