Average without direct commands

My assignment is to create a script where when I put a string of numbers into the command window and run the script it will calculate the average of the string of numbers. I am not permitted to use sum or mean in the script. What kind of script would I write? A loop?

The numbers in the command window would have to be assigned to some variable. Then your script can use a for loop to add all the elements of that variable together.

try this...

b=0;
l=length(a);
for k=1:l
    b=b+a(k);
end
m=b/l;

input the string of numbers as a in the command window
