Not Collective

Input Parameter

gll -the nodes

Output Parameter

AA -the stiffness element

Notes: Destroy this with PetscGLLElementAdvectionDestroy()

This is the same as the Gradient operator multiplied by the diagonal mass matrix

You can access entries in this array with AA[i][j] but in memory it is stored in contiguous memory, row oriented
