All Known Subinterfaces:

CholeskyDecompositionResult, LUDecompositionResult, QRDecompositionResult, SVDecompositionResult

All Known Implementing Classes:

CholeskyDecompositionCommonsResult, CholeskyDecompositionOpenGammaResult, LUDecompositionCommonsResult, QRDecompositionCommonsResult, SVDecompositionCommonsResult
```
public interface DecompositionResult
```
Contains the results of matrix decomposition.
The decomposed matrices (such as the L and U matrices for LU decomposition) are stored in this class. There are methods that allow calculations to be performed using these matrices.
