matrix of zeros and ones within number of zeros in each rows in-between a limit

want to have a 30x40 matrix of zeros and ones; however in each row total number of 'ones' must be within 10 to 20.

A = zeros(40,30);
Omin = 10; Omax = 20;  
for i = 1:size(A, 2)
r = randperm(40); 
ind = r(1:(Omin-1) + randi(Omax - Omin +1)) + (i-1)*40;
A(ind) = 1; 
end
A = A';
imshow(A)
sum(A,2)

Thank you for your reply, I got the approach and have the solution

A=zeros(30,40);
for i = 1:size(A,1) %%in each itr a new row to be modified
r=randperm(40); %%randomizing column index
no1s=randi([10,15]); %%no of "0" to be replace with "1" in that row
index=r(1:no1s); %%getting selected column index to be modified "1"
A(i,index)=1; %%column index been converted to "1"
end

So generate a matrix with random ones and zeros. Discard any rows that fail this test, and regenerate just those rows. WTP?

Since you have not said what the distribution of the number of ones is, I cannot offer a complete solution, but it is simple in any case. If you will have 17 ones in a row, then generate a row vector with 17 ones, and 23 zeros. Then randomly permute the elements.
