I want to shift vector values one by one to the left

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

What about this:

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

I already had an idea of shifting but it does not fullfill the requirement that i want.

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
