Method Detail

newL

protected final it.unimi.dsi.fastutil.doubles.DoubleArrayList newL(int size)

Description copied from class: AbstractGenericMatrix

Returns a new data store with given size and entries carrying the default value. The latter depends on the types: false for boolean, 0 for int, 0.0 for double and null for GenericMatrix's.

Specified by:

newL in class AbstractGenericMatrix<double[],it.unimi.dsi.fastutil.doubles.DoubleArrayList>

Returns:

new D[size]

initL

protected final int initL(double[] data,
                          int size)

Specified by:

initL in class AbstractGenericMatrix<double[],it.unimi.dsi.fastutil.doubles.DoubleArrayList>

getDataA

protected double[] getDataA()

Description copied from class: AbstractGenericMatrix

Returns the data store as an array. There are subclasses with array of primitive types.

Specified by:

getDataA in class AbstractGenericMatrix<double[],it.unimi.dsi.fastutil.doubles.DoubleArrayList>

set

public final void set(double value,
                      int... pos)

Set the value resizing by need.

Parameters:

value -

pos -

See Also:

setPlain(double, int)

setPlain

public final void setPlain(double value,
                           int pos)

Set the value assuming resize is not necessary.

Parameters:

value -

pos -

See Also:

set(double, int[])

setPlain

public final void setPlain(String value,
                           int pos)

Description copied from class: AbstractGenericMatrix

Sets the entry with plain position pos to value parsing the string value. Note that this base class cannot provide setter methods for java's primitive data types.

Specified by:

setPlain in class AbstractGenericMatrix<double[],it.unimi.dsi.fastutil.doubles.DoubleArrayList>

pos - see e.g. AbstractObjectMatrix.setPlain(String, int) and setPlain(String, int)

get

public final double get(int... pos)

Get the value.

Parameters:

pos -

Returns:

value at pos

getPlainString

public final String getPlainString(int pos)

Description copied from class: AbstractGenericMatrix

Returns the string representation of the given plain position.

Specified by:

getPlainString in class AbstractGenericMatrix<double[],it.unimi.dsi.fastutil.doubles.DoubleArrayList>

zero

public OctaveDouble zero()

shallowCopy

public OctaveDouble shallowCopy()

Description copied from interface: OctaveObject

Make a shallow copy of this object. In general when an OctaveObject is returned from a getter, e.g. on OctaveStruct or OctaveStruct, a shallow copy is returned in order to follow the way octave behaves. This method is used to make that copy.

Specified by:

shallowCopy in interface OctaveObject

Specified by:

shallowCopy in class AbstractGenericMatrix<double[],it.unimi.dsi.fastutil.doubles.DoubleArrayList>

Returns:

a shallow copy of this
