Classes in org.apache.mahout.math used by org.apache.mahout.math
AbstractMatrix A few universal implementations of convenience functions
AbstractVector Implementations of generic capabilities like sum of elements and dot products
DenseVector Implements vector as an array of doubles
Matrix The basic interface including numerous convenience functions
MatrixSlice
NamedVector
RandomAccessSparseVector Implements vector that only stores non-zero doubles
SequentialAccessSparseVector Implements vector that only stores non-zero doubles as a pair of parallel arrays (OrderedIntDoubleMapping), one int[], one double[].
Vector The basic interface including numerous convenience functions NOTE: All implementing classes must have a constructor that takes an int for cardinality and a no-arg constructor that can be used for marshalling the Writable instance NOTE: Implementations may choose to reuse the Vector.Element in the Iterable methods
Vector.Element A holder for information about a specific item in the Vector.
VectorIterable
VectorList Provides a very flexible matrix that is based on a simple list of vectors.
VectorView Implements subset view of a Vector
