Hi Faustine Enos,
I do not know how your data is available and what data type you chose. It is preferrable to use table type data. Then, you can adjust the following code snippet:
col_1 = {'Country A';'Country A';'Country A';'Country A';'Country B';'Country B';'Country B';'Country C'};
col_2 = [1; 2; 3; 4; 5; 6; 7; 8];
data = table(col_1,col_2,'VariableNames',{'Country','value'});
cCountry = unique(data.Country);
for ik = 1:numel(cCountry)
sumVal(ik) = sum(data.value(ismember(data.Country,cCountry{ik})));
disp(sprintf('%s %d',cCountry{ik},sumVal(ik)));
end
Kind regards,
Robert
