Constructor Detail

DoubleVectorDataDense

public DoubleVectorDataDense(double[] vectorSI)

Create a vector with dense data.

Parameters:

vectorSI - double[]; the data to store

Method Detail

assign

public final void assign(DoubleFunction doubleFunction)

Parameters:

doubleFunction - DoubleFunction; the function to apply on the (mutable) data elements

toSparse

public final DoubleVectorDataSparse toSparse()

Overrides:

toSparse in class DoubleVectorData

Returns:

the sparse transformation of this data

size

public final int size()

Specified by:

size in class DoubleVectorData

Returns:

the size of the vector

getSI

public final double getSI(int index)

Specified by:

getSI in class DoubleVectorData

Parameters:

index - int; the index to get the value for

Returns:

the value at the index

setSI

public final void setSI(int index,
                        double valueSI)

Sets a value at the index in the vector.

Specified by:

setSI in class DoubleVectorData

Parameters:

index - int; the index to set the value for

valueSI - double; the value at the index

getDenseVectorSI

public final double[] getDenseVectorSI()

Specified by:

getDenseVectorSI in class DoubleVectorData

Returns:

a safe copy of VectorSI

copy

public final DoubleVectorDataDense copy()

Specified by:

copy in class DoubleVectorData

Returns:

a deep copy of the data.

incrementBy

public final void incrementBy(DoubleVectorData right)
                       throws ValueException

Add a vector to this vector on a cell-by-cell basis. The type of vector (sparse, dense) stays the same.

Specified by:

incrementBy in class DoubleVectorData

Parameters:

right - DoubleVectorData; the other data object to add

Throws:

ValueException - if vectors have different lengths

decrementBy

public final void decrementBy(DoubleVectorData right)
                       throws ValueException

Subtract a vector from this vector on a cell-by-cell basis. The type of vector (sparse, dense) stays the same.

Specified by:

decrementBy in class DoubleVectorData

Parameters:

right - DoubleVectorData; the other data object to subtract

Throws:

ValueException - if vectors have different lengths

multiplyBy

public final void multiplyBy(DoubleVectorData right)
                      throws ValueException

Multiply a vector with the values of another vector on a cell-by-cell basis. The type of vector (sparse, dense) stays the same.

Specified by:

multiplyBy in class DoubleVectorData

Parameters:

right - DoubleVectorData; the other data object to multiply with

Throws:

ValueException - if vectors have different lengths

divideBy

public final void divideBy(DoubleVectorData right)
                    throws ValueException

Divide the values of a vector by the values of another vector on a cell-by-cell basis. The type of vector (sparse, dense) stays the same.

Specified by:

divideBy in class DoubleVectorData

Parameters:

right - DoubleVectorData; the other data object to divide by

Throws:

ValueException - if vectors have different lengths
