mikera.matrixx.impl

Interface IFastColumns

All Superinterfaces:

java.lang.Cloneable, java.lang.Comparable<INDArray>, IMatrix, INDArray, java.io.Serializable

All Known Implementing Classes:

BroadcastVectorMatrix, ColumnMatrix, DenseColumnMatrix, IdentityMatrix, PermutationMatrix, RowMatrix, SparseColumnMatrix, UpperTriangularMatrix, ZeroMatrix

public interface IFastColumns
extends IMatrix

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