*Please write a Matlab friendly answer so i can input on my computer

Write a function called classAverage that takes in an array of numbers and, after normalizing the grades in such a way that the highest corresponds to 100, returns the letter grade of the class average. The grade ranges are as follows:

                  Average>90 =>    A

                  80<=average<90                  B

                  70<=average<80                  C              

                  60<=average<70                  D              

                  average<60                             F

For example:

                  classAverage( [70 87 95 80 80 78 85 90 66 89 89 100] ) should return B

                  classAverage( [50 90 61 82 75 92 81 76 87 41 98 31] ) should return C

                  classAverage( [10 17 55 60 50 38 25 40 36 19 39 10] ) should return F

Explanation / Answer

MATLAB code:

clear all
close all
clc
x=input('Enter nummbers in array : ');
y= mean(x);
if y >90
    disp('A')
elseif y>80 && y<90
    disp('B')
elseif y>70 && y<80
    disp('c')
elseif y>60 && y<70
    disp('D')
elseif y<60
    disp('F')
end
