public interface PhysicalStore<N extends Comparable<N>>
extends MatrixStore<N>, TransformableRegion<N>, Access1D.Collectable<N,Mutate1D>

PhysicalStore:s, as opposed to MatrixStore:s, are mutable. The vast majority of the methods defined here return void and none return PhysicalStore or MatrixStore.

This interface and its implementations are central to ojAlgo.

Method Details

asList

List<N> asList()

Description copied from interface: Access1D

An (immutable) List delegating to this Access1D.

Specified by:

asList in interface Access1D<N extends Comparable<N>>

Returns:

The elements of the physical store as a fixed size (1 dimensional) list. The elements may be accessed either row or colomn major.

See Also:

• Access1D.toList()

indexOfLargestInColumn

default int indexOfLargestInColumn(int row,
 int col)

indexOfLargestInRow

default int indexOfLargestInRow(int row,
 int col)

indexOfLargestOnDiagonal

default int indexOfLargestOnDiagonal(int row,
 int col)

modifyAny

default void modifyAny(Transformation2D<N> modifier)

Specified by:

modifyAny in interface Mutate2D.ModifiableReceiver<N extends Comparable<N>>

Specified by:

modifyAny in interface TransformableRegion<N extends Comparable<N>>

substituteBackwards

void substituteBackwards(Access2D<N> body,
 boolean unitDiagonal,
 boolean conjugated,
 boolean hermitian)

Will solve the equation system [A][X]=[B] where:

• [body][this]=[this] is [A][X]=[B] ("this" is the right hand side, and it will be overwritten with the solution).
• [A] is upper/right triangular

See Also:

• SubstituteBackwards.invoke(double[], int, int, int, Access2D, boolean, boolean, boolean)

substituteForwards

void substituteForwards(Access2D<N> body,
 boolean unitDiagonal,
 boolean conjugated,
 boolean identity)

Will solve the equation system [A][X]=[B] where:

• [body][this]=[this] is [A][X]=[B] ("this" is the right hand side, and it will be overwritten with the solution).
• [A] is lower/left triangular

See Also:

• SubstituteForwards.invoke(double[], int, int, int, Access2D, boolean, boolean, boolean)

supplyTo

default void supplyTo(TransformableRegion<N> receiver)

Specified by:

supplyTo in interface Access2D.Collectable<N extends Comparable<N>,TransformableRegion<N extends Comparable<N>>>

Specified by:

supplyTo in interface MatrixStore<N extends Comparable<N>>

transformLeft

void transformLeft(Householder<N> transformation,
 int firstColumn)

transformLeft

void transformLeft(Rotation<N> transformation)

As in MatrixStore.premultiply(Access1D) where the left/parameter matrix is a plane rotation.

Multiplying by a plane rotation from the left means that [this] gets two of its rows updated to new combinations of those two (current) rows.

There are two ways to transpose/invert a rotation. Either you negate the angle or you interchange the two indeces that define the rotation plane.

See Also:

• transformRight(Rotation)

transformRight

void transformRight(Householder<N> transformation,
 int firstRow)

transformRight

void transformRight(Rotation<N> transformation)

As in MatrixStore.multiply(MatrixStore) where the right/parameter matrix is a plane rotation.

Multiplying by a plane rotation from the right means that [this] gets two of its columns updated to new combinations of those two (current) columns.

There result is undefined if the two input indeces are the same (in which case the rotation plane is undefined).

See Also:

• transformLeft(Rotation)
