For this homework question I am asked to write a program using the while loop that will display a given row or column vector in reverse.

if v is the vector:
n=length(v);
while n>0
disp(v(n));
n=n-1;
end

Supposed the length of your vector is L. Then you want to copy position j to position L-j+1 in the new vector. For example, length 6, position 1 gets written to position 6-1+1 = 6; position 2 gets written to position 6-2+1 = 5, position 3 to position 6-3+1 = 4, and so on.

In your code above,
k=length(v);
and then
L = k;
and then entry k of input corresponds to entry L-k+1 of output.
