Multiple if condition inside multiple for loops

hi I am having some problems. I need to apply 3 conditions simultaneously. but I don't understand that it is correct or not. I am attaching the data files and matlab code which I wrote. Can anybody help please .Please check if statement. Actually I want to find indices 'k' and 'm' with the condition 'k<m' and then use these indices in computation of our main variable u_c.
%%%% Construction of U
u_c(1)=u(1); u_c(N+1)=u(N+1);
for i=2:N
for m=2:N
for k=2:N
if (((z(k-1)+z(k))/2)<((x(i-1)+x(i))/2)<((z(k+1)+z(k))/2))&&...
(((z(m-1)+z(m))/2)<((x(i+1)+x(i))/2)<((z(m+1)+z(m))/2))&&(k<m)
s_c=0;
for j=k+1:m-1
s_c=s_c+(hnold(j)*u(j));
end
s_c;
u_c(i)=(1/hn(i))*((((z(k+1)+z(k))/2-(x(i-1)+x(i))/2)*u(k))+...
(((-z(m-1)+z(k))/2+(x(i+1)+x(i))/2)*u(m))+s_c);
elseif (((z(m-1)+z(m))/2)<((x(i-1)+x(i))/2)<((z(m+1)+z(m))/2))&&...
(((z(m-1)+z(m))/2)<((x(i+1)+x(i))/2)<((z(m+1)+z(m))/2))
u_c(i)=u(m);
end
break
end
end
break
end

At the first glance, the "if" statements look correct (if only all the parenthesis are correctly paired). However, thanks to the "break" statements, your program will always deal with k=2 and n=2 alone, nothing else.
