Classes
struct	sAM
	Class AM: Definition. More...
Typedefs
typedef struct sAM	AM
	Declaraction of the AM class as the AM structure.
Functions
AM *	AM_ctor (Vmem *vmem, Aprx *taprx)
	The AM constructor.
void	AM_dtor (AM **thee)
	The AM destructor.
void	AM_create (AM *thee)
	Create the following internal Alg structures: A ==> The tangent matrix (linearization operator) M ==> The mass matrix W[] ==> The node vectors.
void	AM_destroy (AM *thee)
	Destroy the following internal Alg structures: A ==> The tangent matrix (linearization operator) M ==> The mass matrix W[] ==> The node vectors.
int	AM_markRefine (AM *thee, int key, int color, int bkey, double elevel)
	Mark a given mesh for refinement.
int	AM_refine (AM *thee, int rkey, int bkey, int pkey)
	Refine the mesh.
int	AM_unRefine (AM *thee, int rkey, int pkey)
	Un-refine the mesh.
int	AM_deform (AM *thee)
	Deform the mesh.
int	AM_read (AM *thee, int key, Vio *sock)
	Read in the user-specified initial mesh given in the "MCSF" or "MCEF" format, and transform into our internal datastructures. Do a little more than a "Aprx_read", in that we also initialize the extrinsic and intrinsic spatial dimensions corresponding to the input mesh, and we also then build the reference elements.
double	AM_assem (AM *thee, int evalKey, int energyKey, int residKey, int tangKey, int massKey, int bumpKey, Bvec *u, Bvec *ud, Bvec *f, int ip[], double rp[])
	Assemble the linearized problem at a given level.

	Assemble the energy functional at the current solution.
void	AM_evalFunc (AM *thee, int number, int block, int numPts, double *pts, double *vals, int *marks)
	Evaluate a finite element function.
void	AM_bndIntegral (AM *thee)
	Perform a boundary integral.
double	AM_evalError (AM *thee, int pcolor, int key)
	Evaluate error in the current solution.
void	AM_applyDiriZero (AM *thee, Bvec *which)
	Apply zero dirichlet condition at a given level.
void	AM_iniGuess (AM *thee, Bvec *which)
	Setup an initial guess at a given level.
int	AM_part (AM *thee, int pkey, int pwht, int ppow)
	Partition the mesh using the matching Alg level.
int	AM_partSet (AM *thee, int pcolor)
