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.

Problem 11.2 You are to create a set of data for each of 7 students. For each student, the data is to include: (1) first and last name of the student (minimum of 10 characters for the name with space between first and last) (2) the course names for the courses taken (4 to 6 courses) with names at least 4 characters long (3) the course letter grade for each course (some with + or - appended) (4) the number of units for each course (1 to 5 units) You are to write and run a MATLAB program to compute the grade point averages (gpa) for the students and print them with the corresponding students name in order from highest to lowest gpa. You are to use the function you created in Problem 11.1 to assist in this computation. You may use any of the methods that were discussed to do this problem.
