I am having trouble with this homework assignment

%1 Exercise
%Write a short code using IF construct
%that assigns a letter grade to a given numerical grade
%Do not use elseif construct, hint: nested if constructs may be useful
%95 < grade A
%86 < grade B <= 95 
%76 < grade C <= 86 
%66 < grade D <= 76 
%0 < grade F <= 66 

I have tried some n basic thing just to see if I can change the grade to a letter value, but I am having trouble. Here is an example.

grade = 97;
if(grade >= 95) 
    disp('A')
end

在 MATLAB Online 中打开

if(grade >= 95) 
    disp('A')
end

is fine as far as it goes, but it does not assign the result to anything.

if grade >= 95
   gradeletter = 'A';
end

But you should be checking whether 95 exactly is 'A' or 'B'

You can learn more about if statements in 10 minutes in MATLAB Onramp (chapter 12). It's free, self-paced, and interactive.

clear;clc;

m=input('tell us how many student there are ? ');

for n=1:m

x=input(['tell us about the ',num2str(n),' student mark ? ']);

if x>95

disp('the grade is : A')

elseif x<95 & x>86

disp('the grade is : B')

elseif x<86 & x>76

disp('the grade is : C')

elseif x<76 & x>66

disp('the grade is : D')

elseif x<66 & x>0

disp('the grade is : F')

end

Why did you post this answer? What does it teach? You're more than welcome to start answering questions, but why post a solution to a homework question without any explanation?
