I want to cut the element in matrix. if i have a matrix like [ 110000111 ] (1x1) i want to make this [ 11 ; 0000 ; 111 ] (3x1) is this possible? If you can only cut it to a certain size, it's okay. like [110000111] to [110 ; 000 ; 111] that's okay too. thks :-)

What is the data type of your input matrix? What is the expected data type of the output matrix?

Change this number to string, so you will can cut.
bio lim

a=[110000111];
b=str2double(regexp(num2str(a),'\d','match'))
count = 1;
for i = 1:3
result(i) = str2num(strcat(num2str(b(count)),num2str(b(count+1)),num2str(b(count+2))));
count = count + 3;
end
result = result'
result =
110
0
111
Since result is double it is not displayed as 000, but 0.
If you keep it as a string without the str2num, then, something like:
result{i} = strcat(num2str(b(count)),num2str(b(count+1)),num2str(b(count+2)));
result =
'110'
'000'
'111'

In the special case where you are working with a string
S = '110000111';
result = regexp(S, '(.)(\1*)(?!\1)', 'match');
