@susila bahri, Is it the number of non-zero element in each row is one, or the sum of each row equals one?

% number of rows:
N = 8;
Here are some example random matrices where each row has one element, which is what you asked for:
rand(N,1) % elements drawn from the uniform distribution between 0 and 1
randn(N,1) % elements drawn from the standard normal distribution
randi([6,9],N,1) % uniformly distributed integers between 6 and 9
