Hi! Can anybody help me with my code?

mass_AnPoll = 0;
for i = 1:5
    mass_AnPoll = mass_AnPoll + mer(1:i);
end

Error Message in Code: "Arrays have incompatible sizes for this operation."

Answer 1

size(mass_AnPoll)
size(mer)

Perhaps you want to append the elements

mass_AnPoll = 0;
for i = 1:5
    mass_AnPoll = [mass_AnPoll, mer(1:i)]; % or [mass_AnPoll; mer(1:i)]
end

If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:

[KSSV]

mass_AnPoll = 0;
for i = 1:5
    mass_AnPoll = mass_AnPoll + mer(1,i);  % mer(1,i) this should be a single number of you index 
end

You can simply also use:

mass_AnPoll = sum(mer(1,1:5))
