How to replace zero with one automatically in MATLAB

Hello everyone , i hope you are doing well.

i have the following code in which i create array of 6000x6 manualy and replace zero with one for every 1000 rows

like first column has ones in 1 to 1000, then second column has ones from 1001 to 2000.

I want it to be done by automatically or single line

Can anybody help me

labels=zeros(6000,6);
labels(1:1000,1)=1;
labels(1001:2000,2)=1;
labels(2001:3000,3)=1;
labels(3001:4000,4)=1;
labels(4001:5000,5)=1;
labels(5001:6000,6)=1;

Here are three approaches:

M1 = repelem(eye(6,6),1000,1)

M1 = 6000×6

1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0

M2 = kron(eye(6,6),ones(1000,1))

M2 = 6000×6

1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0

C = repmat({ones(1000,1)},1,6);
M3 = blkdiag(C{:})

M3 = 6000×6

1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0

isequal(M1,M2,M3) % checking

ans = logical
