In Matlab I need someone to code this

An array grades contains percentages of test grades. Populate a corresponding array with the letter grade: grades = [89, 80, 69, 99, 75, ..., 69, 90]; letterGrades = [];

Solution

% matlab code

% input student grades
grades = [];
grades = input(\"Enter student grades: \");
disp(grades);

letterGrade = [];
for i=1:length(grades)
if grades(i) >= 90
letterGrade(i) = \'A\';
elseif grades(i) >= 80
letterGrade(i) = \'B\';
elseif grades(i) >= 70
letterGrade(i) = \'C\';
elseif grades(i) >= 60
letterGrade(i) = \'D\';
else
letterGrade(i) = \'F\';
end
end
disp(\"Letter gardes: \");
for i=1:length(grades)
fprintf(\"%c \",letterGrade(i));
end
% end matlab code

%{
output:

Enter student grades: [45 56 67 78 89 99]   
45 56 67 78 89 99
Letter gardes:
F F D C B A
