Dear John,

setsearch assumes that the vector is sorted. You can achieve this with v = Set(v).

Dear all,

I would expect the function copied below to return a vector of zeros of length n, for any n. But it doesn't (for me, running Version 2.13.4), for n>9. Can someone explain to me why? and how to "fix" it?

Faithfully,

John

f(n)=
{

local(v,ans);
v=vector(n,i,Str(i));
ans=vector(n,i,setsearch(v,v[i],1));
ans;
