Index in position 2 exceeds array bounds (must not exceed 1).

for elem=1:ne %Calling elements

for i=1:4

for j=1:4

if (elem(i,4)==1)

k=eval(['k',num2str(elem),'l']);

else

k=eval(['k',num2str(elem),'l']);

KG(i,j)=k(i,j)+KG(i,j);

end

end

end

end

Your first line is making "elem" a scalor but the if test is using it as a martix; this does not work.
