How to separate the figures of specific number and then making a new vector which will include the figures that have been separated separately ?? for example : if i have a number as (123456789) , what is the function or command that will separate these figures of the number so that they look like this form 1 2 3 4 5 6 7 8 9 Meaning that will turn into a vector

Try this:
n = 123456789;
% Convert to a string.
strn = num2str(n)
% Initialize with all spaces.
output = char(32*ones(1,2*length(strn)))
% Make every other character the digits from the number.
output(1:2:end) = strn

output is a vector. It's a row vector of type character. And it stops at 9 because that's what you asked for when you said you want it to "look like this form 1 2 3 4 5 6 7 8 9". Please explain why my solution is not giving exactly what you asked for. 9 was your last digit and that's where it stopped. Where would you want it to stop at? Perhaps give a second example if that would help.

Perhaps you want the characters converted back to numbers? If so, try
n=123456789
str =num2str(n)
strn = regexp(str,'\d','match')
str2double(strn)
