Lk=input('input test grades for Luke : ');
La=input('input test grades for Leia: ');
An=input('input test grades for Anakin: ');
disp(sum(Lk))
disp(sum(La))
disp(sum(An))
DATA:
Luke [98 85 88]
Leia [94 90 80]
Anakin [84 78 100]
I need to use a loop so that it reads "(students name) received a total of (total points) points on the three quizzes."

Then you need to use an array for the input variables instead of separately-named variables so you can address them by subscript instead of by name...

To use a for loop, you'd need to store those in a container such as a structure array or cell array. So if s is your structure array, with fields name, and scores, then
s(1).name = 'Luke'
s(1).scores = [98 85 88]
s(2).name = 'Leia'
s(2).scores = [94 90 80]
s(3).name = 'Anakin'
s(3).scores = [84 78 100]
for k = 1 : length(s)
fprintf('%s received a total of %d points on the %d quizzes.\n',...
s(k).name, sum(s(k).scores), length(s(k).scores));
end
