Interface IFastRows

All Superinterfaces:

Cloneable, IMatrix, INDArray, Serializable

All Known Implementing Classes:

ADenseArrayMatrix, AVectorMatrix, BroadcastVectorMatrix, ColumnMatrix, IdentityMatrix, ImmutableMatrix, LowerTriangularMatrix, Matrix, PermutationMatrix, RowMatrix, SparseRowMatrix, VectorMatrixM3, VectorMatrixMN, ZeroMatrix

public interface IFastRows
extends IMatrix

Marker interface for matrices with fast row access General intention is that any matrix that implements this must have a fast getRow(), typically - O(1) time and space - An efficient vector type returned (a strided vector or better)
