Subscript indices must either be real positive integers or logicals.

i got this error in this code i don't know why.
c=[x(1:end-1,:),x(2:end,:)];
dx=c(:,2)-c(:,1);
t=[y(1:end-1,:),y(2:end,:)];
dy=t(:,2)-t(:,1);
ra=[];
rb=[];
for i=1:size(dx)
if dx(2i-1)>0 & dy(2i)<0;
ra(2i-1)=1;
ra(2i)=1;
end
if dy(2i-1)>0 & dx(2i)<0;
rb(2i-1)=1;
rb(2i)=1;
end
end

Which line is the error on? You can use the stop/pause on errors debug option from the Breakpoints menu to have the code stop at the line causing the error. Then it is trivial to work out what is wrong by looking at any subscript indices you are using in the command window.

It's hard to tell without having some input, but these types of lines are definitely wrong:
ra(2i)=1;
i is being interpreted as imaginary, which is why you should not use i as a looping variable.
ans =
0.0000 + 2.0000i
Could be other errors as well.
