NUMERICAL DIFFERENTIAL EQUATION ANALYSIS PACKAGE SYMBOL
GaussianQuadratureWeights
gives a list of the n pairs 
of the elementary n-point Gaussian formula for quadrature on the interval a to b, where 
is the weight of the abscissa 
.
attempts to give a result with prec digits of precision.
Details
- To use
, you first need to load the Numerical Differential Equation Analysis Package using Needs["NumericalDifferentialEquationAnalysis`"]. - Gaussian quadrature approximates the value of an integral as a linear combination of values of the integrand evaluated at optimal abscissas
: 
. - The abscissas are optimal in the sense that the quadrature formula is exact for all polynomials up to degree
.
