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"

range integrals"

cheers
