 Demonstrate diagonalized mass matrices for H(grad) elements in 1d using Gauss-Legendre quadrature.
 
file  example_06.cpp [code]
 Matrix-free application of the Laplace stiffness matrix for polynomials of degree d on an NX x NY mesh. We are using a reference element stiffness matrix and level 3 BLAS for the application, but not using any tensor-product decomposition.
 
file  example_07.cpp [code]
 Example building stiffness matrix for a Poisson equation using nodal (Hgrad) elements on squares. This shows how to use the local-global mapping to preallocate the matrix graph. This leads to an improvement in the time it takes to construct the global matrix.

 Example building stiffness matrix and right hand side for a Poisson equation using nodal (Hgrad) elements on squares. This code transforms the basis function gradients to each cell and performs quadrature.

file  example_10.cpp [code]
 Construction of Laplace operator on a uniform hexahedral mesh using arbitrary-degree elements. This is the most naive implementation wherein we form the stiffness matrix on each cell by quadrature and do not preallocate the global matrix graph before assembling.
 
file  example_11.cpp [code]
 Construction of Laplace operator on a uniform hexahedral mesh using arbitrary-degree elements. This is the second most naive implementation wherein we form the stiffness matrix on each cell by quadrature, but we do preallocate the global matrix graph before assembling.
 
file  example_12.cpp [code]
 Construction of Laplace operator on a uniform hexahedral mesh using arbitrary-degree elements. We preallocate the global matrix graph, and then construct a single element stiffness matrix that is replicated across all cells.
