length

public int length()

Specified by:

length in interface IVector

Specified by:

length in class AVector

elementSum

public double elementSum()

Description copied from class: AVector

Returns the sum of all elements in a vector

Overrides:

elementSum in class AVector

Returns:

get

public double get(int i)

Specified by:

get in interface IVector

Specified by:

get in class AVector

set

public void set(int i,
       double value)

Specified by:

set in interface IVector

Specified by:

set in class AVector

clone

public Vector0 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

isMutable

public boolean isMutable()

Description copied from class: AVector

Returns true if this vector is mutable.

Overrides:

isMutable in class APrimitiveVector

Returns:

hashCode

public int hashCode()

Overrides:

hashCode in class AVector

isZeroVector

public boolean isZeroVector()

Description copied from class: AVector

Returns true if this vector is a zero vector (all components zero)

Overrides:

isZeroVector in class AVector

Returns:

magnitudeSquared

public double magnitudeSquared()

Overrides:

magnitudeSquared in class AVector

magnitude

public double magnitude()

Description copied from class: AVector

Returns the magnitude (Euclidean length) of the vector

Overrides:

magnitude in class AVector

Returns:
