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
