Help with function with nested ifs

It produces errors past 120 cols, but works perfectly fine for a matrix of 1x120.

function [v] = Deflection_klle(x) %Deflection_klle will calculate the deflection of a defined beam % v=Deflection % x=Position

if (x>=0 & x<=120) v=(1/(3.19*10^9)).*((800.*(x.^3))-(13.68.*(10^6).*x)-(2.5.*(x.^4)));

elseif (x>120 & x<=240) v=(1/(3.19*10^9)).*((800.*(x.^3))-(13.68.*(10^6).*x)-(2.5.*(x.^4))+(2.5.*((x-120).^4)));

elseif (x>240 & x<=360) v=(1/(3.19*10^9)).*((800.*(x.^3))-(13.68.*(10^6).*x)-(2.5.*(x.^4))+(2.5.*((x-120).^4))+(600*((x-240).^3))); else end

end

function [v]=Deflection_klle(x)
%Deflection_klle will calculate the deflection of a defined beam 
% v=Deflection 
% x=Position
if (x>=0 && x<=120) 
    v=(1/(3.19*10^9)).*((800.*(x.^3))-(13.68.*(10^6).*x)-(2.5.*(x.^4)));
elseif (x>120 && x<=240) 
    v=(1/(3.19*10^9)).*((800.*(x.^3))-(13.68.*(10^6).*x)-(2.5.*(x.^4))+(2.5.*((x-120).^4)));
elseif (x>240 && x<=360) 
    v=(1/(3.19*10^9)).*((800.*(x.^3))-(13.68.*(10^6).*x)-(2.5.*(x.^4))+(2.5.*((x-120).^4))+(600*((x-240).^3))); else end
end
