	Hi!

	Relating gsl_poly_eval and gsl_sf_poly_eval, and if I understood
correctly the reply mail, I should use *gsl_poly_eval*. Now, the
question is: does this function works? I receive, always a 0.0000
return value. Can anybody show an example, where is returns a
different value?

	Thanks

	Alberto

it worked for me. perhaps you can post an example of how you get all the 0's. be
sure to compile with most warnings (-Wall and friends) turned on!

Yes.

This function should work, it is tested in poly/test.c.  If there is
still a problem after looking there can you send more details about
your configuration thanks.
