```
public class QuantileSortSPInstruction
extends UnarySPInstruction
```
This class supports two variants of sort operation on a 1-dimensional input matrix. The two variants are weighted and unweighted . Example instructions: sort:mVar1:mVar2 (input=mVar1, output=mVar2) sort:mVar1:mVar2:mVar3 (input=mVar1, weights=mVar2, output=mVar3)
