I am trying to find the perturbations in my data based on a 30 minute time average for 24 hour data.
My original data has 1728000 rows, divided by 48 is 36000. So each of the 36000 entries need to subtract value 1 from the other table, the next 36000 entries will subtract value 2. I have tried for loops and I can't get anything to work past the 36000 entries.
I need something to perform the following:
big_table.uprime(1:36000) = big_table.B_Ux_2(1:36000) - thirtymin.u30(1);
big_table.uprime(36001:72000) = big_table.B_Ux_2(36001:72000) - thirtymin.u30(2);
and so on
