Re: [Help-gsl] permutation

[Inigo Aldazabal Mensa]

Hi,

If you just want combinations with the elements allowed to repeat, as in your 
{0,1} sample, I think you can do it yourself with just four nested for loops 
all of them running from 1 to 4...

Something as...

for (n1=1; n1<=4; n1++)
   for (n2...)
      for (n3...)
         for (n4...){
            print (n1 n2 n3 n4)
         }


Regards, 

Iñigo
