Let say I have an array
A = [ 0 0 0 0 1 2 3 4 5 6 7 8 9 0 0 0 0 ]
I would like to know wheter is there any way to move starting four zeros to the end of same array A.
The result should be
Result = [ 1 2 3 4 5 6 7 8 9 0 0 0 0 0 0 0 0 ]
Now, in this example there were only four zeros. I do have arrays which have more than 4 zeros.
Thanks

Try this:
A = [0 0 0 0 1 2 3 4 5 6 7 8 9 0 0 0 0];
idx = find(A>0,1);
B = [A(idx:end),zeros(1,idx-1)]

n=find(A,1);
Result=circshift(A,1-n);

Try this
A = [ 0,1,0,3,12];
idx = 1;
for j = 1 : numel(A)
if A(j) ~= 0
% swap A(j) and A(idx)
A([j idx]) = A([idx j]);
idx = idx + 1;
end
end
