Create a Calender matrix

Hi all, I have a quick question. I have gridded data I am trying to manipulate and for the sake of existing code I have written (that had this type of index with the data embedded in the netcdf file) would like to create an auxillary matrix with the corresponding time

For instance, I have 12,xxx indexes that correspond to each day between Jan 1, 1979 to Dec 31, 2011

I would like to create a 4x12,xxx array that is of the following behavior

(Record, Month, Day, Year) where each one is 12,xxx in length

Record is the raw index value (1-12,xxx)
Month is the coressponding month of the index value (ie 31 consecutive 1's for Janurary, 28 consecutive 2s for Feb, etc and repeats)
Day is the corresponding day (1-28(31)) for the index
Year is the corresponding year (365 consecutive 1979, then 365 1980s, etc)

Is there an easy way to make this type of array? I would need to take into accoun the leap years and what not

Thanks for any tips

 

I am creating the array in matlab. The 12,xxx is more explicitly 12,053 values

here is how I initially approached the problem.

Code:

%% Calender maker

record = [1:1:12053];

y79 = [1:1:365];
y80 = [1:1:366];
y81 = [1:1:365];
y82 = [1:1:365];
y83 = [1:1:365];
y84 = [1:1:366];
y85 = [1:1:365];
y86 = [1:1:365];
y87 = [1:1:365];
y88 = [1:1:366];
y89 = [1:1:365];
y90 = [1:1:365];
y91 = [1:1:365];
y92 = [1:1:366];
y93 = [1:1:365];
y94 = [1:1:365];
y95 = [1:1:365];
y96 = [1:1:366];
y97 = [1:1:365];
y98 = [1:1:365];
y99 = [1:1:365];
y00 = [1:1:366];
y01 = [1:1:365];
y02 = [1:1:365];
y03 = [1:1:365];
y04 = [1:1:366];
y05 = [1:1:365];
y06 = [1:1:365];
y07 = [1:1:365];
y08 = [1:1:366];
y09 = [1:1:365];
y10 = [1:1:365];
y11 = [1:1:365];

day = [y79,y80,y81,y82,y83,y84,y85,y86,y87,y88,y89,y90,y91,y92...
    y93,y94,y95,y96,y97,y98,y99,y00,y01,y02,y03,y04,y05,y06,...
    y07,y08,y09,y10,y11]';

I have netcdf files with length of the record dimension and am trying to manipulate it via data so hence my complimentary matrix I am attempting to recreate if that makes sense

Edit: Figured it out...even though my code to generate it is not the most elagant!
