Hello everyone, I am working on climate data and I have a matrix size of 12x361, (where the 12 represents the months and 361 represents the columns).
Now i want to repeat the factor values of each corresponding months (Jan-Dec) of the 361 stations into 30years (say 1931 to 1961) on the daily wise.
For example i have "Jan" month factor value of 0.778, "Feb" month is 0.65, "Mar" is 0.56 ....and Dec is 0.69, Now i want to repeat the each factor value
of the particular months into days and into 30years for all the 361 stations and the data should be arranged serially (say Jan-1931, Feb-1931... Dec-1960)
I have tried the code below shown for your reference and required your valuable suggestions to proceed further.
load BCC_CF_Mul_pr_1961.mat
b=BCC_CF_Mul_pr_1961(:,1:361); %12rows of factor values for all the 361 stations
% Inserts Year and Months
x=bsxfun(@(Month,Year) datenum(Year,Month,1),(1:12).',1931:1960);
x=x(:);
d=datevec(x);
d=d(:,1:2);
%inserting number of days in a month of the year
a1=eomday(d(:,1),d(:,2));
%Repeat the evry month of the factor values to the days caculated from the previous step
a2=repmat(b(1),a1(1),1); %this line repeats the values only for that month
Kindly help me to proceed further
Thank you

I'm not sure, what you are asking for. With some guessing:
a1 = eomday(d(:,1),d(:,2));
index = repelem((1:size(b, 1)).', a1);
a2 = b1(index, :);

@Nataraja M: As far as I can see, this is a new question. Then, as said already, open a new thread to ask it. This is better than attaching a new question as a comment in another thread.
"how to do the same in the matlab using the below code" - this is hard to answer, because I do not really understand what you have done with which other software. Please post, what the inputs are and what you need as output.
