This problem exercises the reading and writing of excel spreadsheets. 1. Use the xlsread() function to read the numerical data from the file grades.xlsx into an array called scores, and the text data from the file into an array called names. 2. Use disp() to display the names to the command window. (Matlab will store the text data in a cell array, which we have not covered yet. We won't ask you to do anything more with it at this point.) 3. Perform the following statistical calculations on the scores and store them in a row vector called grade_stats: mean, median, mode, standard deviation, minimum, maximum. (They must be stored in the vector in the specified order. Use help if you are unfamiliar with the Matlab functions to perform these operations. 4. Use the csvwrite() function to write the grade_stats array to a spreadsheet file called grade_stats.csv. (Unfortunately xlswrite does not work in Grader. However, the syntax of csvwrite is the same.) The template will read the contents of your written spreadsheet file to verify its contents.
