out = regexprep('qwe hj l',' ','   ')

or

a = regexp('qwe hj l',' ','split');
out = cell2mat(cellfun(@(x)[x,blanks(length(x))],a,'un',0))

thanks ,
but the result is not what I need
when use regexprep, I got
qwe hj l

i have long sequences, this is just example , I need something more general.
i.e I need code palce '-' in any space find it.
I can not get the index of spaces, this is my problem.
ex. z='qwe hj l';
for i=1:length(j)
if z(i)==' '
z(i)='-'
end
end
this is code did not get the spaces, also when use if z(i)==[].
So, how I can get the index of spaces?
i tried use if
