The LinearSOE object assembles fact
times the Matrix M
into the matrix $A$.
The Matrix is assembled into $A$ at the locations given by the ID object loc
, i.e. $a_{loc(i),loc(j)}+= M(i,j)$. Numbering in $A$ starts at $(0,0)$, i.e. C style. If allocation specified is outside the range, i.e. $(-1,-1)$ the corresponding entry in M
is not added to $A$. To return $0$ if successful, a negative number if not.
Implements XC::LinearSOE.
|
virtual |
The LinearSOE object assembles fact
times the Vector V
into the vector $b$.
The Vector is assembled into $b$ at the locations given by the ID object {loc}, i.e. $b_{loc(i)} += V(i)$. If a location specified is outside the range, e.g. $-1$, the corresponding entry in {V} is not added to $b$. To return $0$ if successful, a negative number if not.
Implements XC::LinearSOE.
|
virtual |
Receive the object.
Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through cp
. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using #theBroker. To return 0 if successful or a -1 if not.
Implements XC::MovableObject.
|
virtual |
Send the object.
Each object has to send the data needed to be able to reproduce that object in a remote process. The object uses the methods provided by cp
object to send the data to another channel at the remote actor, the address of the channel is set before this method is called. An object of similar type at the remote actor is invoked with a receiveSelf() to receive the data. Returns 0 if successful (successful in that the data got to the channel), or a - if no data was sent.
Implements XC::MovableObject.
|
virtual |
The LinearSOE object sets the vector b
to be fact
times the vector V
.
To return $0$ if successful, a negative number if not.
Implements XC::LinearSOE.
|
virtual |
Determines and sets the size of the system.
Invoked to allow the LinearSOE object to determine the size and sparsity of the matrix $A$ and vectors $x$ and $b$. This information can be deduced from the number of vertices and the connectivity between the vertices in the Graph object theGraph
. To return $0$ if successful, a negative number if not.
Implements XC::LinearSOE.
|
virtual |
The LinearSOE object is responsible for setting \(x(loc) = value\).
This is needed in domain decomposition methods and could be useful in iterative solution strategies when an initial approximation is known.
Implements XC::LinearSOE.
|
virtual |
Computes the solution of the system of equations.
Causes the SystemOfEqn object to invoke solve() on the currently associated solver object. Returns a $0$ if successful, negative number if not; the actual value depending on the LinearSOESolver. To solve a linear system of equations means to find $x$ such that the equation $Ax=b$ is satisfied.
Reimplemented from XC::LinearSOE.
