public subroutine ply_gaussLegPoints(x1, x2, x, w, nIntP)

Create Gauss-Legendre integration points and weights for one-dimensional integration on the interval [x1,x2].

Arguments

TypeIntentOptionalAttributesName
real(kind=rk), intent(in) :: x1

lower limit of integration interval
real(kind=rk), intent(in) :: x2

upper limit of integration interval
real(kind=rk), intent(out) :: x(:)

The coordinates of the gauss points on the interval [x1,x2]. The array has the length nIntP.
real(kind=rk), intent(out) :: w(:)

The quadrature weights. The array has the length nIntP.
integer, intent(in) :: nIntP

The number of integration points.
