5. Letter grade calculator Write a function with first line function [grade] =myLetterGrader (percent) where grade is the string 'A+' if percent is bigger than 97, 'A, if percent is bigger than 93, 'A-' if percent is bigger than 90, 'B+ if percent is bigger than 87, B if percent is bigger than 83, B-' if percent is bigg D+ if percent is bigger than 67, 'D if percent is bigger than 63 for any percent lower than 60. Grades exactly on the division should be included in the higher grade category C+, if percent is bigger than 77,'C' if percent is bigger than 73, 'c-' if percent is bigger than 70, , D- if percent is bigger than 60, and 'F Test Cases: >> grade = myLetterGrader (97) grade A+ >> grade = myLetterGrader(84) grade
