Another approach is to use two Gaussian quadrature rules of different orders, and to estimate the error as the difference between the two results.

This allows for computing higher-order estimates while re-using the function values of a lower-order estimate. Aufl. Numer. It is accurate for polynomials up to degree 2nâ€“3, where n is the number of integration points (Quarteroni, Sacco & Saleri 2000).

Gaussâ€“Lobatto rules[edit] Also known as Lobatto quadrature (Abramowitz & Stegun 1972, p.888), named after Dutch mathematician Rehuel Lobatto. monic orthogonal polynomials) satisfy the recurrence relation p r + 1 ( x ) = ( x − a r , r ) p r ( x ) − a r The trapezoidal rule returns the integral of the orange dashed line, equal to y ( − 1 ) + y ( 1 ) = − 10 {\displaystyle y(-1)+y(1)=-10} .

MathWorld. The domain of integration for such a rule is conventionally taken as [âˆ’1, 1], so the rule is stated as ∫ − 1 1 f ( x ) d x = We can write ∏ 1 ≤ j ≤ n j ≠ i ( x − x j ) = ∏ 1 ≤ j ≤ n ( x − x j ) For computing the weights and nodes, it is preferable to consider the symmetric tridiagonal matrix J {\displaystyle {\mathcal {J}}} with elements J i , i = J i , i =

"A Gaussian quadrature for the calculation of generalized Fermi-Dirac integrals". Since the degree of f(x) is less than 2n-1, the Gaussian quadrature formula involving the weights and nodes obtained from p n ( x ) {\displaystyle p_{n}(x)} applies. Eng. Equation numbers are given for Abramowitz and Stegun (A & S).

To prove this, note that using Lagrange interpolation one can express r(x) in terms of r ( x i ) {\displaystyle r(x_ Î¾ 6)} as r ( x ) = ∑ Lobatto quadrature of function f(x) on interval [âˆ’1, 1]: ∫ − 1 1 f ( x ) d x = 2 n ( n − 1 ) [ f ( 1 Golub, Gene H.; Welsch, John H.
