RandomProjectionFamily.Projection (ELKI: Environment for DeveLoping KDD-Applications Supported by Index-Structures)

All Known Implementing Classes:

AbstractRandomProjectionFamily.MatrixProjection, RandomSubsetProjectionFamily.SubsetProjection, SimplifiedRandomHyperplaneProjectionFamily.SignedProjection

Enclosing interface:

RandomProjectionFamily
```
public static interface RandomProjectionFamily.Projection
```
Interface for projection instances (not thread safe). To enable the use of internal buffers for faster multiplication, this code is currently not thread safe.
