Detailed Description

template<class Scalar, class ArrayPoint = FieldContainer<Scalar>, class ArrayWeight = ArrayPoint>
class Intrepid::CubatureLineSorted< Scalar, ArrayPoint, ArrayWeight >

Utilizes cubature (integration) rules contained in the library sandia_rules (John Burkardt, Scientific Computing, Florida State University) within Intrepid.

This class contains ten rules:

Gauss-Chebyshev Type 1 - integration domain is [-1,+1] with weight w(x) = 1/sqrt(1-x^2)
Gauss-Chebyshev Type 2 - integration domain is [-1,+1] with weight w(x) = sqrt(1-x^2)
Clenshaw-Curtis - integration domain is [-1,+1] with weight w(x) = 1
Fejer Type 2 - integration domain is [-1,+1] with weight w(x) = 1
Gauss-Legendre - integration domain is [-1,+1] with weight w(x) = 1
Gauss-Patterson - integration domain is [-1,+1] with weight w(x) = 1
Trapezoidal - integration domain is [-1,+1] with weight w(x) = 1
Gauss-Hermite - integration domain is (-oo,+oo) with weight w(x) = exp(-x^2)
Hermite-Genz-Keister - integration domain is (-oo,+oo) with weight w(x) = exp(-x^2)
Gauss-Laguerre - integration domain is [0,+oo) with weight w(x) = exp(-x)
