Detailed Description

Class that describes how a flat blocked operator should be reordered.

Class that describes how a flat blocked operator should be reordered. The semenatics are very similar to a Teuchos::ParameterList. Each level expects you to set the size of the level and define what each subblock is. For example, to change the blocked 3x3 matrix from

$ Z = \left[\begin{array}{ccc} A & B & C \\ D & E & F \\ G & H & I \end{array}\right]$

to

$ Z' = \left[\begin{array}{cc} \left[\begin{array}{cc} A & B \\ D & E \end{array}\right] & \left[\begin{array}{c} C \\ F \end{array}\right] \\ \left[\begin{array}{cc} G & H \end{array}\right] & I \end{array}\right]$

the algorithm to build the appropriate block manager is

RCP<BlockReorderManager> bmm = rcp(new BlockReorderManager(2));
bmm->GetBlock(0)->SetNumBlocks(2);
bmm->GetBlock(0)->SetBlock(0,0);
bmm->GetBlock(0)->SetBlock(1,1);
bmm->SetBlock(1,2);

Suppose now you want to take your $Z$ operator and build $Z'$. The relevant code is

BlockedLinearOp Z = ...
LinearOp Zprime = buildReorderedLinearOp(*bmm,Z);

Use the BlockReorderManager to change a flat vector space into a composite vector space.

Use the BlockReorderManager to chanage a flat vector space a more complex composite structure. The manager should not have any indicies larger then the size of the blocked operator.

Parameters
[in]mgrBlockReorderManager that specifies how the space is to be restructured.
