I want to extract cell array

I do have 1x7 cell arraiy which contain 5488x4. 1st col is year, 2nd col is month, 3rd isday and 4th is the dily rainfall. I want to extract the daily data from each cell and make other cell aray contain 7 daily rainfall elements. How can I do the code? here is my data

it is my trial

for i=1:length(unistsrfr1)
    for j = 1:5844
        dy_strfr1= rfdata_tsstrfr1{1,i}(1:j,4);
        yy= rfdata_tsstrfr1{1,1}(1:j,1);
        mm= rfdata_tsstrfr1{1,1}(1:j,2);
        dd= rfdata_tsstrfr1{1,1}(1:j,3);
        datenum(yy,mm,dd,0,0,0)
    end 
end

[Walter Roberson]

rf_cell = cellfun(@(C) [datenum(C(:,1), C(:,2), C(:,3)), C(:,4)], unistsrfr1, 'uniform', 0);

The result, rf_cell, will be a 1 x 7 cell array, each entry of which is a 5488 x 2 double, with the first column containing the datenum and the second column containing the rainfall.

Note: these days we recommend that you use datetime() objects instead of datenum()

[Habtamu Tsegaye]

The result, rf_cell, will be a 1 x 7 cell array, each entry of which is a 5488 x 2 double. I do not need 5488X2double. what I need is 1X7 or 7X1 rainfall elements taken (one by one) from each 1X7cell array in the data attached.
