I have a 5000x1 vector and am trying to write a function to calculate an answer for entry 1-11, then 12-22, then 23-33, etc. ... I've been trying to use a 'for' loop, basically: for i = (???????) x=i+1 end Not sure what to put in the ???? area. I want it to spit out answers for each set of 11 values, but can't figure out how.
