In Matlab

• Create function gpa_cal( grades, hours) to compute gpa and total hours
• Inputs
  • Grades is array of letter grades e.g, grades =[ABBC]
  • Hours is array of course hours g., hours =[4 3 3 3]
  • For each grade, convert to grade points (A=4, , F=0)
• gpa = sum(pts.* hours)/sum(hours)
• Test cases
  • Grades =[ACCB], hours=[3 4 3 3]
  • Grades = [BACB], hours=[4 1 3 3]
