I would like to create a random matrix with the following constraints:
- all values should be Integer values
- fixed row sums (decreasing with row e.g. 100, 50, 10, 5 etc.)
- random values from 0 to 6
I tried to create a random matrix and scale it to my fixed row sums I want, but then I get the problem that I get Float values (rounding does not help either)
A = rand(0:6, 5, 10)
sum_vec = [10,5,3,2,2]
for i = 1:length(A[:,1])
# row sum
s = sum(A[i,:])
A[i,:] = (A[i,:] /s ) * sum_vec[i]
end
Thanks a lot for your help!
