INT_EXACTNESS_GEN_HERMITE: User input: Quadrature rule X file = "gen_herm_o1_a1.0_x.txt". Quadrature rule W file = "gen_herm_o1_a1.0_w.txt". Quadrature rule R file = "gen_herm_o1_a1.0_r.txt". Maximum degree to check = 5 Weighting function exponent ALPHA = 1.00000 Spatial dimension = 1 Number of points = 1 The quadrature rule to be tested is a generalized Gauss-Hermite rule ORDER = 1 A = -0.179769 ALPHA = 1.00000 OPTION = 0, standard rule: Integral ( -oo < x < oo ) |x|^alpha * exp(-x^2) * f(x) dx is to be approximated by sum ( 1 <= I <= ORDER ) w(i) * f(x(i)). Weights W: w( 1) = 1.000000000000000 Abscissas X: x( 1) = 0.000000000000000 Region R: r( 1) = -0.1797693134862000 r( 2) = 0.1797693134862000 A generalized Gauss-Hermite rule would be able to exactly integrate monomials up to and including degree = 1 Error Degree Exponents 0.0000000000000000 0 0 0.0000000000000000 1 1 1.0000000000000000 2 2 0.0000000000000000 3 3 1.0000000000000000 4 4 0.0000000000000000 5 5 INT_EXACTNESS_GEN_HERMITE: Normal end of execution. 7 September 2007 10:34:15.458 AM
