. I want the script file in matlab.

Write a script file that computes theGPA for a list of courses. The number of courses can vary. The credits for each course can vary. Shaded grading should be used.The script should ask for a letter grade and then ask for the associated credits.It will then repeat as needed.The script should ask for new courses until the user inputs a blank(indicating they are done).If the user makes a typo a message should be printed and the program should continue.The script should output the total grade points, the total credits, and the resulting GPA.

Explanation / Answer

%matlab script

totalCredits = 0;
totalGradePoints = 0;

while true
courseName = input('Enter course name: ', 's');
if isempty(courseName)
break
end
  
grade = input('Enter letter grade: ', 's');
credits = input('Enter credits: ');
  
if grade == 'A'
totalGradePoints = totalGradePoints + 5*credits;
elseif grade == 'B'
totalGradePoints = totalGradePoints + 4*credits;
elseif grade == 'C'
totalGradePoints = totalGradePoints + 3*credits;
elseif grade == 'D'
totalGradePoints = totalGradePoints + 2*credits;
elseif grade == 'E'
totalGradePoints = totalGradePoints + 1*credits;
else
totalGradePoints = totalGradePoints + 0;
end
  
totalCredits = totalCredits + credits;
end

GPA = totalGradePoints/totalCredits;
fprintf('GPA: %0.2f ',GPA);

%{
output:

Enter course name: maths
Enter letter grade: A
Enter credits: 3
Enter course name: bio
Enter letter grade: C
Enter credits: 4
Enter course name: chemistry
Enter letter grade: B
Enter credits: 3
Enter course name:
GPA: 3.90
