I'm trying to help my Fiance with her problem(I'm on her account) for her engineering programming class. I know a good bit about C++ and Java but I'm completely unaccustomed to MATLAB and so I'm not doing all that well helping her. Does anyone know how to do this? I would greatly appreciate the help, I've looked but there doesn't seem to be anything online that's the same. She has to use the mean and std deviation functions in the program as well.

The following code might help
clear all;
clc;
a=input('Enter the grades');
len = length(a);
m=mean(a);
sdev = std(a);
fprintf('There are %d grades\n',len);
In the Command window input the grades inside square bracket separated by comma.
