I will write the sequence clearly

'qwe hj l'

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

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

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
