Package com.singularsys.exttests.matrix

Class RationalMatrixFactory

java.lang.Object

com.singularsys.extensions.matrix.genericmat.GenericMatrixFactory<Rational>

com.singularsys.exttests.matrix.RationalMatrixFactory

All Implemented Interfaces:

MatrixFactoryI, JepComponent, Serializable

public class RationalMatrixFactory
extends GenericMatrixFactory<Rational>

A MatrixFactory where the matrices have elements of type Rational. and calculations are performed using the RationalField. Here the matrices are actually an array Rational[][] rather than array Object[][] where the elements are all rationals.

RationalMatrixFactory

public RationalMatrixFactory(RationalField base)

Method Details

cast

protected RationalMatrixFactory.RationalMatrix cast(MatrixI m)

Description copied from class: GenericMatrixFactory

A typical implementation will just use return (GenericMatrix<E>) m;

Overrides:

cast in class GenericMatrixFactory<Rational>

Parameters:

m - the matrix to cast

Returns:

a matrix of type GenericMatrix<E> = GenericMatrix<E>

cast

protected RationalMatrixFactory.RationalVector cast(VectorI m)

Description copied from class: GenericMatrixFactory

A typical implementation will just use return (V) v;

Overrides:

cast in class GenericMatrixFactory<Rational>

Parameters:

m - the vector to cast

Returns:

a vector of type V = GenericVector<E>

buildDataArray

protected Rational[][] buildDataArray(int rows,
 int cols)

Description copied from class: GenericMatrixFactory

Build a data array. A typical concrete implementation will just use return new E[rows][cols].

Overrides:

buildDataArray in class GenericMatrixFactory<Rational>

Parameters:

rows - number of rows

cols - number of cols

Returns:

the array.

buildDataArray

protected Rational[] buildDataArray(int len)

Description copied from class: GenericMatrixFactory

Build a data array. A typical concrete implementation will just use return new E[rows][len].

Overrides:

buildDataArray in class GenericMatrixFactory<Rational>

Parameters:

len - number of elements

Returns:

the array.

newMatrixUnchecked

public RationalMatrixFactory.RationalMatrix newMatrixUnchecked(Object[][] data)

Overrides:

newMatrixUnchecked in class GenericMatrixFactory<Rational>

newVectorUnchecked

public RationalMatrixFactory.RationalVector newVectorUnchecked(Object[] data)

Overrides:

newVectorUnchecked in class GenericMatrixFactory<Rational>
