get_gauss_legendre

QuadratureRule get_gauss_legendre ( int  , int    )

friend

Computes or accesses a precomputed 1D quadrature rule of Gauss-Legendre points.

Parameters

[in]

npts

The number of points in the rule

A Gauss-Legendre rule with npts points can exactly integrate polynomials of order 2 * npts - 1

Note

If this method has already been called for a given order, it will reuse the same quadrature points without needing to recompute them

Returns

The QuadratureRule object which contains axom::ArrayView<double>'s of stored nodes and weights
