Detailed Description

Computed k-norm of matrix.

int sc::SCElementKNorm::has_collect () [virtual]

If duplicates of the SCElementOp exist (that is, there is more than one node), then if has_collect returns nonzero then collect is called with a MessageGrp reference after all of the blocks have been processed. The default return value of has_collect is 0 and collect's default action is do nothing. If defer_collect member is called with nonzero, collect will do nothing (this is only used by the blocked matrices).

Reimplemented from sc::SCElementOp.

void sc::SCElementKNorm::process (SCMatrixBlockIter &) [virtual]

This is the fallback routine to process blocks and is called by process_spec members that are not overridden.

Implements sc::SCElementOp.

void sc::SCElementKNorm::save_data_state (StateOut &) [virtual]

Save the base classes (with save_data_state) and the members in the same order that the StateIn CTOR initializes them. This must be implemented by the derived class if the class has data.

Reimplemented from sc::SavableState.
