Multiple Values for one variable with for loop

Hey guys, I'm new to MATLAB so please be gentle. I'm trying to give x multiple values to assign multiple characters depending on a for loop. As you can see I need to store every value of the row vector (x) as a character; it only stores the last value (90)

x = [80 50 70 60 50 90];

for x = [80 50 70 60 50 90];
    
if x>=80
    grade = 'D';
    
elseif (x>=60) && (x<80)
    grade = 'M';
     
else 
    grade = 'P';
    
    end
disp(grade)
grade 
end

No need for a loop. Just use discretize().

Grades=["P" "M" "D"];

x = [80 50 70 60 50 90];

binNumber=discretize(x,[-inf,60,80,inf]),

binNumber = 1×6

3 1 2 2 1 3

grades=Grades(binNumber)

grades = 1×6 string array
    "D"    "P"    "M"    "M"    "P"    "D"

I must use a loop as a part of an assignment

[Matt J]

Same kind of thing with a loop would be,

Grades=["P" "M" "D"];

x = [80 50 70 60 50 90];

N=numel(x);

grade=strings(1,N);
for i=1:N
    
    binNumber=discretize(x(i),[-inf,60,80,inf]);
    
    grade(i) = Grades(binNumber);
    
end 

grade

grade = 1×6 string array
    "D"    "P"    "M"    "M"    "P"    "D"
