HOW TO REMOVE THE ERROR

actually i am trying to do some binning in matlab .i am newbie in matlab so i dont know how to remove the error i have tried to sort out the problem but could not worked out. showing a error- SUBSCRIPT INDICES MUST EITHER BE REAL POSITIVE INTEGERS OR LOGICALS.

    % code
  endpoints=50; %separation btw points
bin=5
L=size(E)
minE=min(E)
maxE=max(E)
counter=0
for i=0:points:L
E(counter)=mean(E(i:i+bin));
if i+bin>L
break 
end
dN=sum(n(i:i+bin));
dE=E(i+bin)-E(i)
if dE==0
dE=epsi
end
dn_o_dE(counter)=dN/dE
counter=counter+1
end

// Assemble the mechanism module ratchet_pawl_mechanism() { ratchet_wheel(); pawl(); cam_profile(); }

// Display the full mechanism ratchet_pawl_mechanism();

MATLAB does NOT use zero based indexing.

However, in several places, you index with a variable that takes on that value. For example, in this line alone:

E(counter)=mean(E(i:i+bin));

both the counter variable and i start out as 0.

READ THE ERROR MESSAGE!

"SUBSCRIPT INDICES MUST EITHER BE REAL POSITIVE INTEGERS OR LOGICALS."

When last I checked, 0 was not a positive integer. Don't do that, and your problems will go away.

i have changed counter=0 to 1, but what should i do with for loop case when i dont know the initial points how can i directly change it to 1 from zero,its a user interface so it will change again and again

    % code
  for i=0:points:L
