Question

Matlab Question (Matlab Grader).

Suppose a course letter grade is assigned per the following scheme:

Letter Grade______ Course Numerical Grade Interval

A _______________[90,100]

B_______________ [80,90)

C_______________ [70,80)

D_______________ [60,70)

F_______________ [0.60)

Write a function, called coursegrade, that takes one non-negative input, numgrade, and assigns an output, letgrade, which is the corresponding letter grade character value, i.e, 'A', 'B', etc... , assigned per the scheme above. Assume that the input will always be a non-negative number less than or equal to 100.

Use on if statement containing several elseif's and one else in your code.

Note that the script is set up to call and test your function.

Answer 1

Code:

function letter_grade = coursegrade(num_grade)
if num_grade >= 90
letter_grade = "A";
elseif (num_grade >= 80) && (num_grade < 90)
letter_grade = "B";
elseif (num_grade >= 70) && (num_grade < 80)
letter_grade = "C";
elseif (num_grade >= 60) && (num_grade < 70)
letter_grade = "D";
else
letter_grade = "F";
end
  
end

Output:

>> letter_grade = coursegrade(75)

letter_grade =

"C"

>> letter_grade = coursegrade(90)

letter_grade =

"A"

>> letter_grade = coursegrade(55)

letter_grade =

"F"

>>
