Write a function that accepts an input vector of integer exam scores and outputs a two column cell array with the same number of rows as the input vector. Each cell in the first column should contain a score from the input vector. The cells in the second column should have strings that give the corresponding letter grade according to the following grading scale:

Score values ranging from 90 to 100 receive an A.

Score values ranging from 80 to 89 receive a B.

Score values ranging from 70 to 79 receive a C.

Score values ranging from 60 to 69 receive a D.

Score values ranging from 0 to 59 receive an F.
