Detailed Description

class hp1D::LinearFormHelper< 1, F >

Helper class for linearforms l(v), where v is a 1-form.

$\displaystyle l(v) = \int\limits_K f(x)^\top v\,dx = \int\limits_{\hat{K}} f(F_K(\xi))^\top \hat{v}\,\circ F_K^{-1} \,d\xi$

$F_K$ is the element mapping from reference element $\hat{K} = [0,1]$ . $v$ is for a example the derivative of a shape function, and $\hat{v}$ the derivative of the local corresponding local shape function.
