how to generate a RANDOM matrix of 0's and 1's such that the number of 1's in any column is the same.

The positioning of 0's and 1's across the matrix should be random. At the same time, the number of 1's should be fixed. Something like this {1 0 1 0 1 0; 0 1 0 1 0 0; 1 0 1 0 1 0; 0 1 0 1 0 1; 0 0 0 0 0 1 0 0 0 0 0 0} I tried using randperm randi .but I am not getting equal number of 1's Thanks in advance

n=6
A=zeros(n)
m=2   % number of 1 per column
for k=1:n
  idx=randperm(n,m)
  A(idx,k)=1
end

numCol = 5;
numOnes = 3;
numRows = 10;
result = ones(numRows,numCol);

for ii = 1:numCol
    result(:,ii) = randperm(numRows) <= numOnes;
end

n=6
m=2
A=zeros(n)
A(cell2mat(arrayfun(@(x) randperm(n,m)+6*x,0:n-1,'un',0)))=1
