data type from gmm:
: .

inlinevirtual |
Add value
to the element (i,j). Throws an error if the entry does not exist. Still, it is allowed to store zero values in non-existent fields.
Implements Feel::MatrixSparse< T >.
|
inline |
Add the full matrix to the Petsc matrix. This is useful for adding an element matrix at assembly time
|
inline |
Same, but assumes the row and column maps are the same. Thus the matrix dm
must be square.
|
virtual |
Add a Sparse matrix _X
, scaled with _a
, to this

Return the l1-norm of the matrix, that is , (max. sum of columns).
This is the natural matrix norm that is compatible to the l1-norm for vectors, i.e. .

|
inlinevirtual |
Return the value of the entry (i,j). This may be an expensive operation and you should always take care where to call this function. In order to avoid abuse, this function throws an exception if the required element does not exist in the matrix.
In case you want a function that returns zero instead (for entries that are not in the sparsity pattern of the matrix), use the el
function.
Implements Feel::MatrixSparse< T >.
|
virtual |
Print the contents of the matrix in Matlab's sparse matrix format. Optionally prints the matrix to the file named name
. If name
is not specified it is dumped to the screen.
