str = num2str([17;10],'%05i')
if length(str(1,:))==5,
%%%here is your command
end
or
str = num2str([17;10],'%05i')
if numel(str(1,:))==5,
%%%here is your command
end

Better to use NUMEL, for generality.
S = ['ertyu';'poiuy';'lkjhg';'nbvcx']
length(S)
numel(S)

>>a='string'; >>n=length(a) so n will return length of a string
