Package org.apache.sysds.runtime.controlprogram.parfor

## Class ResultMergeMatrix

- java.lang.Object
- - org.apache.sysds.runtime.controlprogram.parfor.ResultMerge<MatrixObject>
  - - org.apache.sysds.runtime.controlprogram.parfor.ResultMergeMatrix

- All Implemented Interfaces:
    `Serializable`
  Direct Known Subclasses:
    `ResultMergeLocalAutomatic`, `ResultMergeLocalFile`, `ResultMergeLocalMemory`, `ResultMergeRemoteSpark`, `ResultMergeRemoteSparkWCompare`

      public abstract class ResultMergeMatrix
      extends ResultMerge<MatrixObject>

  Due to independence of all iterations, any result has the following properties: (1) non local var, (2) matrix object, and (3) completely independent. These properties allow us to realize result merging in parallel without any synchronization.
