/** Epetra Finite-Element CrsMatrix. This class provides the ability to
input finite-element style sub-matrix data, including sub-matrices with
non-local rows (which could correspond to shared finite-element nodes for
example). This class inherits Epetra_CrsMatrix, and so all Epetra_CrsMatrix
functionality is also available.
It is intended that this class will be used as follows:
<ul>
<li> Construct with either a map or graph that describes a (non-overlapping)
data distribution.
<li> Input data, including non-local data, using the methods
InsertGlobalValues(), SumIntoGlobalValues() and/or ReplaceGlobalValues().
<li> Call the method GlobalAssemble(), which gathers all non-local data
onto the owning processors as determined by the map provided at
construction. Users should note that the GlobalAssemble() method has an
optional argument which determines whether GlobalAssemble() in turn calls
FillComplete() after the data-exchange has occurred. If not explicitly
supplied, this argument defaults to true.
***NOTE***: When GlobalAssemble() calls FillComplete(), it passes the
arguments 'DomainMap()' and 'RangeMap()', which are the map attributes
held by the base-class CrsMatrix and its graph. If a rectangular matrix
is being assembled, the correct domain-map and range-map must be passed to
GlobalAssemble (there are two overloadings of this method) -- otherwise, it
has no way of knowing what these maps should really be.
</ul>
Sub-matrix data, which is assumed to be a rectangular 'table' of
coefficients accompanied by 'scatter-indices', can be provided in three
forms:
<ul>
<li>Fortran-style packed 1-D array.
<li>C-style double-pointer, or list-of-rows.
<li>Epetra_SerialDenseMatrix object.
</ul>
In all cases, a "format" parameter specifies whether the data is laid out
in row-major or column-major order (i.e., whether coefficients for a row
lie contiguously or whether coefficients for a column lie contiguously).
See the documentation for the methods SumIntoGlobalValues() and
ReplaceGlobalValues().
Important notes:
<ol>
<li> Since Epetra_FECrsMatrix inherits Epetra_CrsMatrix, the semantics of
the Insert/SumInto/Replace methods are the same as they are on
Epetra_CrsMatrix, which is:
<ul>
<li>InsertGlobalValues() inserts values into the matrix only if the graph
has not yet been finalized (FillComplete() has not yet been called). For
non-local values, the call to InsertGlobalValues() may succeed but the
GlobalAssemble() method may then fail because the non-local data is not
actually inserted in the underlying matrix until GlobalAssemble() is called.
<li>SumIntoGlobalValues() and ReplaceGlobalValues() only work for values
that already exist in the matrix. In other words, these methods can not be
used to put new values into the matrix.
</ul>
</ol>

arguments 'DomainMap()' and 'RangeMap()', which are the map attributes
held by the base-class CrsMatrix and its graph. If a rectangular matrix
is being assembled, the domain-map and range-map must be specified by
calling the other overloading of this method. Otherwise, GlobalAssemble()
has no way of knowing what these maps should really be.
