Problem 11.1 Write and run a MATLAB function that has as input, a letter grade that can include + or - with the letter grades A, B, C, but not with the D or F. The output of the function is to be the numerical equivalent of the letter grade, that is an A or A+ converts to a 4, A- = 3.7, B+ = 3.3, B = 3, B- = 2.7, C+ = 2.3, C = 2, C- = 1.7, D = 1, F = 0.

Solution

Quite a simple code using switch case statement

function grades
clc
clear all

grades= input(\'Enter number to corresponding grades 1.A+ 2.A- 3. B+ 4.B 5. B- 6.C+ 7. C 8.C- 9. D 10. F : \')   
switch grades
case {1}
disp (\'CGPA = 4\')
case {2}
disp (\'CGPA = 3.7\')

case {3}
disp (\'CGPA = 3.3\')

case {4}
disp (\'CGPA = 3.0\')
case {5}
disp (\'CGPA = 2.7\')
case {6}
disp (\'CGPA = 2.3\')
case {7}
disp (\'CGPA = 2\')
case {8}
disp (\'CGPA = 1.7\')
case {9}
disp (\'CGPA = 1\')
case {10}
disp (\'CGPA = 0\')
otherwise
disp (\'Enter right option\')
end
