Re: Fast random numbers

[Max Görner]

Thank you for your fast reply. Below you can find a script showing two 
scenarios. The script also shows that the runtime is not due to memory 
assignment or writing.

   #!/usr/bin/octave --no-init-file
   
   n = 4.6E7;
   k = 0.72*n;
   tic(); randperm(n, k); toc() #1.7 seconds
   tic(); 1337 + zeros(1, k); toc() #0.2 seconds
   
   n = 10000;
   tic(); rand(n); toc() #1.7
   tic(); 1337 + zeros(n); toc() #0.7


Sincerely

Max Görner
