division of a single column matrix

i have a single column matrix A=0 0 0 1 1 1 1 0 0 0 0 2 2 2 2 0 0 0 0 1 1 1 now i have to divide this in to several matrices such whenever 0 changes to 1 or 2 i want a new matrix in this case A1= 1 1 1 1 0 0 0 0; A2=2 2 2 2 0 0 0 0 ;A3= 1 1 1 which are also single column matrices ............using for loop

See my double edited answer in the previous post.

in this case

A = A(:);
I = cumsum([0;diff(A)]~=0 & (A == 1 | A == 2));
out = arrayfun(@(x)A(I==x),1:max(I),'un',0);

Dear bilhan! I think it is necessary to remove the question. See commentary by Oleg Komarov

Hi Oleg, i'm to blame, did not notice.

You can add your answer to the other post. Multiple interpretations are always useful.
