rearranging in a matrix

Hi, i got a question.

i got a code that eventually produces matrices like these:

x = [1 1 0 0 ];

with a n number of 1's in front followed by k number of 0's.

now im trying to rearrange it to:

x2 = [1 0 1 0]

or another example:

x = [1 1 1 1 0 0 0]

to

x2 = [1 0 1 0 1 0 1]

i hope you get the gist.

sorry if it's a bit vague, my first time posting here!

One approach —

x = [1 1 0 0 ];
xr = reshape(buffer(x,nnz(x)).', 1, []);
xr = xr(1:numel(x))

xr = 1×4

1 0 1 0

x = [1 1 1 1 0 0 0];
xr = reshape(buffer(x,nnz(x)).', 1, []);
xr = xr(1:numel(x))

xr = 1×7

1 0 1 0 1 0 1

Experiment to get different results.
