Dear Nora, here is the code which reads the file and then shows information for people having blood group 'AB':
ID = fopen('filename.txt');
a = textscan(ID, '%s%s%s%s%f');
fclose(ID)
firstname = a{1};
lastname = a{2};
bloodtype = a{3};
Rhfactor = a{4};
IDnumber = a{5};
info{1, 1} = 'First name';
info{1, 2} = 'Last name';
info{1, 3} = 'Blood type';
info{1, 4} = 'Rh factor';
info{1, 5} = 'ID number';
count = 2;
for i = 1:length(bloodtype)
if bloodtype{i} == 'AB'
info(count, 1) = firstname(i);
info(count, 2) = lastname(i);
info(count, 3) = bloodtype(i);
info(count, 4) = Rhfactor(i);
info{count, 5} = IDnumber(i);
count = count + 1;
end
end
disp('People with blood group AB are:')
disp(info)
I hope it helps. Good luck!
