solve it using MATLAB and include all steps please

The vector G = [68, 83, 61, 70, 75, 82, 57, 5, 76, 85, 62, 71, 96, 78, 76, 68, 72, 75, 83, 93] represents the distribution of final grades in a dynamics course. Compute the mean, median, mode, and standard deviation of G. Which better represents the "most typical grade, " the mean, median, or mode? Why? Use MATLAB registered sign to determine the number of grades in the array (don't just count them) and to sort them into ascending order
