Index in position 2 exceeds array bounds?

I wrote the at the beginning of my code

jaywalk=zeros(1,n);

then I changed the values in jaywalk

at the end of my code, I wrote

for i=1:n
    if jaywalk(1,i)==1
        disp(plate(i));
    end
end

when I run the code, matlab always tell me 'Index in position 2 exceeds array bounds'

how can i solve the problem?

Any help will be appreciated! Thanks!

what is the return value of size(plate)?

[KSSV]

m = length(jaywalk) ;
n = length(plate) ;
if m ~= n 
  error("length of jaywalk and plate should be same")
else
  for i=1:n
    if jaywalk(i)==1
        disp(plate(i));
    end
  end
end

If dimensions of jaywalk and plate are same, you can striaght away use indexing instead of loop.

plate(jaywalk==1)  % this will display value of plate when jaywalk == 1
