How can I loop an array from the end to the beginning, with a while loop?

Hi,

I have a words array with 6 words in it. Like:

array= { 'A' 'B' 'C' 'D' 'E''F' 'G'} ;

I have to display the words one by one, but from the end to the beginning ( so from G to A), by using a while loop. Up till now I have got the following script:

ArrayLength = numel(wordsArray);

i=ArrayLength;

while (i > 0)

    i= i-1;

    words= wordsArray(i); 

    disp(words)
end

This script however only displays the words G to B and I get the following error:

??? Subscript indices must either be real positive integers or logicals.

Error in ==> vraag5 at 16 words= wordsArray(i);

Can anyone please help me out with this?

   ii = length(array);
   while (ii>0)
   disp(array{ii}); 
   ii = ii-1;
   end
