Update of bug #32237 (project gsl):
Status: In Progress => Fixed
_______________________________________________________
Follow-up Comment #1:
I just ran into this need too...
In revision 4711 I implemented gsl_integration_glfixed_point to allow
retrieving Gauss-Legendre points and weights from a
gsl_integration_glfixed_table. The points are strictly increasing which
should allow you to compare them against other implementations. Test cases in
integration/test.c check their validity for n = 1, 2, 3, 4, and 5 against some
analytic results as well as ensuring they're scaled correctly for non-[-1,1]
intervals. Both pass on GCC's -O3.
I'm closing this feature. Please re-open if you run into any trouble.
