extracting data from set of data

hi there so i have this set of data :

all_data1 = importdata("owid-covid-data_2020-21.csv");
num_data1 = all_data1.data;
text_data1 = all_data1.textdata;
days_tarcked= num_data1(:,1);
total_case= num_data1(:,2);
total_death= num_data1(:,3);
code_id = string(text_data1((2:end),1));
continent = string(text_data1((2:end),2));
location_countries = string(text_data1((2:end),3));
data_countries = string(text_data1((2:end),4));

that is about the days tracked by different countries for tracking there number of cases, and im trying to extract the countries that didnt have at leaset 396 entries for there days track from variable days track and location_countries.

any hint or suggestions will be appreciated.

t=readtable('owid-covid-data_2020-21.csv');
u=unique(t.Location);
count=0;
for k=1:length(u)
    m=movsum(diff(t.TotalCases(ismember(t.Location,u(k)))),3);
    if all(m<396)
        count=count+1;
        C{count}=u{k};
    end
end
