Extract cell rows to new array after strfind or strcmp matching.

Hi everyone, I have an array of data (500*7) and the 7th column is a series of date array, they are all in random order so I would like to rearrange by month_array. So for each cell matching the portion of string '01/2015' i want a loop that extract the all rows (1:7) for example and store it in a new array etc. I have included a picture to ease the understanding.

          jan_table = [];
          for i=1:size(ship_table);
              idx = strfind(ship_table(i,7),'01/2015');
              if idx isequal('4')
                  STORE ROW IN NEW ARRAY jan_table
              else
                  jan_table = [jan_table num2cell(ships_table{i})];
              end
          end

If anyone could help, thanks!
