SUMMARY

The Gauss-Kronrod quadrature employs the zeros of Legendre Polynomials of degree n and Stieltjes Polynomials of degree n+1 to determine nodes for integration. Specifically, using the Gauss polynomial of degree 7 necessitates the Stieltjes polynomial of degree 8, resulting in a total of 15 nodes according to the quadrature rule (2n+1). The discussion highlights the challenge of calculating weights from these nodes, contrasting it with the more straightforward process of determining weights for Gauss-Legendre quadrature.

TL;DR
How to compute the weights once you have the nodes?
The Gauss-Kronrod quadrature uses the zeros of the Legendre Polynomials of degree n and the zeros of the Stieltjes polynomials of degree n+1. These zeros are the nodes for the quadrature. For example using the Gauss polynomial of degree 7, you will need the Stieltjes of degree 8 and both makes up to 15 nodes in accordance to the quadrature rule (2n+1).

But how would you calculate the weights given the nodes and the degree?

I tried but nothing comes in handy.

For example the Gauss-Legendre quadrature weights is easily understood in this link: Legendre weights
So I'm looking for something like this for the Gauss-Kronrod!
 
Relativistic Momentum, Mass, and Energy Momentum and mass (...), the classic equations for conserving momentum and energy are not adequate for the analysis of high-speed collisions. (...) The momentum of a particle moving with velocity ##v## is given by $$p=\cfrac{mv}{\sqrt{1-(v^2/c^2)}}\qquad{R-10}$$ ENERGY In relativistic mechanics, as in classic mechanics, the net force on a particle is equal to the time rate of change of the momentum of the particle. Considering one-dimensional...
