i want to make matrix. for manual way or the output

A=[1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 ... 8 8 8 8 8 8 8 8];

for A, each value until 8 times the value will be add by 1.

b=[1 2 3 4 5 6 7 8 1 2 3 4 5 6 7 8 ... 1 2 3 4 5 6 7 8];

for b, value 1-8 will be looping until 8 times.

so the size A is 1x64 and B is 1x64

A = kron(1:8,ones(1,8));
B = kron(ones(1,8),1:8);

A = reshape(repmat((1:8), 8, 1), 1, [])
b = repmat(1:8, 1, 8)
