Method Detail

wrap

public static Vector wrap(double[] source)

Wraps a double array into a Vector, does *no defensive copy* so use with caution

Parameters:

source -

Returns:

of

public static Vector of(double... values)

createLength

public static Vector createLength(int length)

length

public int length()

Specified by:

length in class AVector

get

public double get(int i)

Specified by:

get in class AVector

set

public void set(int i,
       double value)

Specified by:

set in class AVector

getArray

public double[] getArray()

Specified by:

getArray in class ArrayVector

getArrayOffset

public int getArrayOffset()

Specified by:

getArrayOffset in class ArrayVector

fill

public void fill(double value)

Description copied from class: AVector

Fills a vector with a given value

Overrides:

fill in class AVector

add

public void add(ArrayVector v)

Overrides:

add in class ArrayVector

addMultiple

public void addMultiple(ArrayVector v,
               double factor)

Overrides:

addMultiple in class ArrayVector

add

public void add(AVector v)

Description copied from class: AVector

Adds another vector to this one

Overrides:

add in class AVector

sub

public void sub(AVector v)

Description copied from class: AVector

Subtracts a vector from this vector

Overrides:

sub in class AVector

subtract

public void subtract(ArrayVector v)

addMultiple

public void addMultiple(AVector v,
               double factor)

Description copied from class: AVector

Adds a scaled multiple of another vector to this one

Overrides:

addMultiple in class AVector

multiply

public void multiply(double factor)

Description copied from class: AVector

Multiplies the vector by a constant factor

Overrides:

multiply in class AVector

Parameters:

factor - Factor by which to multiply each component of the vector

isReference

public boolean isReference()

Description copied from class: AVector

Returns true if this vector is of a type that references other vectors / data.

Overrides:

isReference in class AVector

Returns:

clone

public AVector clone()

Description copied from class: AVector

Clones the vector, creating a new copy of all data. The clone is: - not guaranteed to be of the same type. - guaranteed to be fully mutable - guaranteed not to contain a reference (i.e. is a full deep copy)

Overrides:

clone in class AVector
