Hi Mohd! Your last comment - new question.

[Andrei Bobrov]

Xy = [1 1 1 2 2 2 2 4 5 5].'

[out,subs,subs] = unique(Xy)

k = accumarray(subs,ones(numel(subs),1))

out = [out k/sum(k)*100]

wow.. the command is really successful but can you explain a little bit from your command. i'm very interesting to know and learn from you. a million thanks to you andrei bobrov:-)

can you explain this code.

Xy = [1 1 1 2 2 2 2 4 5 5].'

[out,subs,subs] = unique(Xy)

k = accumarray(subs,ones(numel(subs),1))

out = [out k/sum(k)*100]
