mikera.matrixx.impl.AVectorMatrix<T>

All Implemented Interfaces:

Cloneable, Iterable<AVector>, INDArray, IMatrix, ITransform

Direct Known Subclasses:

VectorMatrixM3, VectorMatrixMN

public abstract class AVectorMatrix<T extends AVector>
extends AMatrix

Abstract base class for matrices that use a collection of Vectors as storage for the matrix rows. Vector matrices support appending with new rows - this functionality can be useful e.g. when building a matrix to represent a data set.

AVectorMatrix

public AVectorMatrix()

Method Detail

appendRow

public abstract void appendRow(AVector row)

getRow

public abstract T getRow(int row)

Gets a row of the matrix. Should be guaranteed to be an existing vector by all descendents of VectorMatrix.

Overrides:

getRow in class AMatrix

get

public double get(int row,
         int column)

Description copied from class: AMatrix

Returns a specified element in the matrix

Specified by:

get in interface INDArray

Specified by:

get in interface IMatrix

Specified by:

get in class AMatrix

Returns:

set

public void set(double value)

Description copied from interface: INDArray

Sets all elements of an array to a specific double value

Specified by:

set in interface INDArray

Overrides:

set in class AMatrix

set

public void set(int row,
       int column,
       double value)

Description copied from class: AMatrix

Sets a specified element in the matrix

Specified by:

set in interface INDArray

Specified by:

set in interface IMatrix

Specified by:

set in class AMatrix

transform

public void transform(AVector source,
             AVector dest)

Description copied from class: ATransform

Transforms the source vector, storing the result in the given destination vector

Specified by:

transform in interface ITransform

Overrides:

transform in class AMatrix

calculateElement

public double calculateElement(int i,
                      AVector inputVector)

Description copied from class: ATransform

Overrides:

calculateElement in class AMatrix

applyOp

public void applyOp(Op op)

Description copied from interface: INDArray

Applies a unary operator to all elements of the array (in-place)

Specified by:

applyOp in interface INDArray
