if i have a row vector like this A=[ 0 1 1 1 0 0 1 1 0 1 ]
and another vector B=[ 1 2 3 4 5 6 ]
and i need to put the element of B in order in A when the element is equal to 1
so if it can possibile i need to return a vector with the dimensions of B like this [ 0 1 2 3 0 0 4 5 0 6 ] , how can i do it if it's possibile to do it in matlab
thank you

Try this:
A=[ 0 1 1 1 0 0 1 1 0 1 ]
B=[ 1 2 3 4 5 6 ]
out = A % Initialize
out(logical(A)) = B % Assign B to "1" locations in A
It give you what you asked for.

[i,j]=find(A(:));
result=accumarray([i,j],B(:),size(A.')).'

I think it's because the poster did not see what she wanted to see. So instead of seeing:
0 1 2 3 0 0 4 5 0 6
like she asked for, you see
result =
(1,2) 1
(1,3) 2
(1,4) 3
(1,7) 4
(1,8) 5
(1,10) 6
