Done.
RandomLinearForm(P) -- if coeff ring of P is F_p
RandomLinearForm(P, n) -- same as RandomLinearForm(P, -n, n)

RandomLinearForm(P, lo, hi) -- lo, hi integers

#4 Updated by John Abbott about 6 years ago

I am not so convinced of the utility of RandomLinearForm(P,lo,hi), and suggest commenting it out until we find a genuine need for it.

OK, I put it in anonymous namespace (it is used by the other two functions)

#6 Updated by John Abbott almost 6 years ago

I have added RandomLinearForm to documentation for SparsePolyRing.

Probably there should also be a version with interface: RandomLinearForm(P, RndSeq) where RndSeq is of type RandomSeqLong (or perhaps RandomSeqBigInt). What do you think?

You are right. Should I do it?
