Method Detail- 
executeSerialMergepublic abstract T executeSerialMerge() Merge all given input matrices sequentially into the given output matrix. The required space in-memory is the size of the output matrix plus the size of one input matrix at a time.- Returns:
- output (merged) matrix
 
 - 
executeParallelMergepublic abstract T executeParallelMerge(int par) Merge all given input matrices in parallel into the given output matrix. The required space in-memory is the size of the output matrix plus the size of all input matrices.- Parameters:
- par- degree of parallelism
- Returns:
- output (merged) matrix
