unit - AU; the unit

Method Detail

mutable

public MA mutable()

Create a mutable version of this DoubleMatrix.
The mutable version is created with a shallow copy of the data and the internal copyOnWrite flag set. The first operation in the mutable version that modifies the data shall trigger a deep copy of the data.

Returns:

MA; mutable version of this DoubleMatrix

                                        AU unit)

Construct a new Absolute Immutable DoubleMatrix of the right type. Each extending class must implement this method.

Parameters:

dmd - DoubleMatrixData; an internal data object

unit - AU; the unit

Returns:

M the Mutable DoubleMatrix of the right type

instantiateTypeRel

protected abstract R instantiateTypeRel(DoubleMatrixData dmd,
                                        RU unit)

Construct a new Relative Immutable DoubleMatrix of the right type. Each extending class must implement this method.

Parameters:

dmd - DoubleMatrixData; an internal data object

unit - RU; the unit

Returns:

M the Mutable DoubleMatrix of the right type

instantiateMutableType

protected abstract MA instantiateMutableType(DoubleMatrixData dmd,
                                             AU unit)

Construct a new Absolute Mutable DoubleMatrix of the right type. Each extending class must implement this method.

Parameters:

dmd - DoubleMatrixData; an internal data object

unit - AU; the unit

Returns:

M the Mutable DoubleMatrix of the right type

instantiateScalar

protected abstract S instantiateScalar(double value,
                                       AU unit)

Construct a new Absolute Immutable DoubleScalar of the right type. Each extending class must implement this method.

Parameters:

value - double; the value

unit - AU; the unit

Returns:

S the Immutable DoubleScalar of the right type

get

public final S get(int row,
                   int column)
            throws ValueException

Retrieve a value from the matrix.

Specified by:

get in interface DoubleMatrixInterface<AU extends AbsoluteLinearUnit<AU,RU>>

Parameters:

row - int; row of the value to retrieve

column - int; column of the value to retrieve

Returns:

the value as a DoubleScalar

Throws:

ValueException - in case row or column is out of bounds

plus

public final A plus(R rel)
             throws ValueException

Add a Relative value to this Absolute value for a vector or matrix. The addition is done value by value and the result is stored in a new Absolute value. If both operands are sparse, the result is a sparse vector or matrix, otherwise the result is a dense vector or matrix.

Specified by:

Parameters:

rel - R; R the right operand

Returns:

A the sum of this vector and the operand

Throws:

ValueException - in case this vector and the operand have a different size

minus

public final A minus(R rel)
              throws ValueException

Subtract a Relative value from this Absolute value for a vector or matrix. The subtraction is done value by value and the result is stored in a new Absolute value. If both operands are sparse, the result is a sparse vector or matrix, otherwise the result is a dense vector or matrix.

Specified by:

minus in interface FunctionsAbs<AU extends AbsoluteLinearUnit<AU,RU>,RU extends Unit<RU>,A extends AbstractDoubleMatrixAbs<AU,RU,A,R,MA,S>,R extends AbstractDoubleMatrixRel<RU,R,?,?>>
