I am trying to perform the following calculation, but every 52 rows the denominator needs to change from (1,1) to (52,1) then (104,1) etc.
Can someone please assist?
rAPf(i,:) = ((tickPf(i,1) / tickPf(1,1))-1)*100;

t = 1 ;
for i = 1:n % n should be your last index
if mod(i,52) == 0
t = i ;
end
rAPf(i,:) = ((tickPf(i,1) / tickPf(t,1))-1)*100;
end
