Hello everyone,
I have a binary vector with five 0 and three 1.
num=[1 1 1 0 0 0 0 0]
and I want to shift each 1 left, shift one value as
num=[1 1 0 1 0 0 0 0]
untill I get a complete shift of the vector values and printing of each vector shift
num=[0 0 0 0 0 1 1 1]
any helpfull code of the above program with nested for loop will be highly appreciated
Thanks

PLEASE STOP POSTING MULTIPLE TIMES. You have posted the exact same question now three times. One I have now closed.

num=[1 1 1 0 0 0 0 0]
num = 1×8
1 1 1 0 0 0 0 0
for i=1:3
num = circshift(num, -1)
end
num = 1×8
1 1 0 0 0 0 0 1
num = 1×8
1 0 0 0 0 0 1 1
num = 1×8
0 0 0 0 0 1 1 1

num = [1 1 1 1 1 0 0 0 0 0] ;
for ii = 1: nnz(num)
num = circshift(num, -1)
end
num = 1×10
1 1 1 1 0 0 0 0 0 1
num = 1×10
1 1 1 0 0 0 0 0 1 1
num = 1×10
1 1 0 0 0 0 0 1 1 1
num = 1×10
1 0 0 0 0 0 1 1 1 1
num = 1×10
0 0 0 0 0 1 1 1 1 1

if you only need the last vector,then use sort function.
sort(yourVectorHere)

Is it what you want?
num = [1 1 0 1 0 1 0 1 0 0];
j = find(num);
m = length(j);
l = (-m+1:0)+(length(num))-j;
q = sum(l)+1;
J = zeros(q,m);
i = 1;
J(i,:) = j;
for k=m:-1:1
for n=1:l(k)
i = i+1;
j(k) = j(k)+1;
J(i,:) = j;
end
end
I = repmat((1:q)',1,m);
B = accumarray([I(:) J(:)],1)
B = 20×10
1 1 0 1 0 1 0 1 0 0 1 1 0 1 0 1 0 0 1 0 1 1 0 1 0 1 0 0 0 1 1 1 0 1 0 0 1 0 0 1 1 1 0 1 0 0 0 1 0 1 1 1 0 1 0 0 0 0 1 1 1 1 0 0 1 0 0 0 1 1 1 1 0 0 0 1 0 0 1 1 1 1 0 0 0 0 1 0 1 1 1 1 0 0 0 0 0 1 1 1

May be this?
num = [1 1 0 1 0 1 0 1 0 0];
j = find(num);
m = length(j);
J=repmat(j,m,1);
for i=m:-1:1
J(m-i+1:end,i) = length(num)+i-m;
end
J = [j; J];
I = repmat((1:m+1)',1,m);
B = accumarray([I(:) J(:)],1)
B = 6×10
1 1 0 1 0 1 0 1 0 0 1 1 0 1 0 1 0 0 0 1 1 1 0 1 0 0 0 0 1 1 1 1 0 0 0 0 0 1 1 1 1 0 0 0 0 0 1 1 1 1 0 0 0 0 0 1 1 1 1 1
