In Reply to: Gaussian quadrature weight of the form 1/(1+x^2) posted by Xuelei Chen on March 29, 1998 at 02:54:10:
: hi, I wonder if there is ready made program or
: calculated abscissas and weights for the Gaussian
: quadrature of the form W(x)=1/(1+x^2), please let
: me know if you know one.
HI,
two references which might be helping (I don't
have them under my eyes so I can't guarantee)

of arbitrary functions"
