Method Summary

Modifier and Type	Method and Description
void	addAt(int i, double v) Adds a value to a specific element of the vector This function does not perform bounds checking, i.e.
double	dotProduct(AVector v) Returns the dot product of this vector with another vector The vectors must have the same length: if not the result is undefined
boolean	equals(AVector v) Returns true if this array is exactly equal to a vector.
double	get(int i) Returns the double value at the specified position in a 1D vector
void	getElements(double[] data, int offset) Copies all elements of this array a double array at the specified offset
void	set(int i, double value) Sets a value at a given position in a mutable 1D array
MatrixIndexScalar	slice(int i) Returns the specified major slice of this array as a view (slice along dimension 0) 0 dimensional slice results are permitted, but attempting to slice a 0 dimensional array will result in an error.
double	unsafeGet(int i) Like get, but performs no bounds checking.
void	unsafeSet(int i, double value) Like set, but performs no bounds checking.

Method Detail

addAt

public void addAt(int i,
                  double v)

Description copied from class: AVector

Adds a value to a specific element of the vector This function does not perform bounds checking, i.e. is an unsafe operation

Overrides:

addAt in class AVector

set

public void set(int i,
                double value)

Description copied from interface: INDArray

Sets a value at a given position in a mutable 1D array

Specified by:

set in interface INDArray

Specified by:

set in interface IVector

Specified by:

set in class AVector

unsafeSet

public void unsafeSet(int i,
                      double value)

Overrides:

unsafeSet in class AVector

get

public double get(int i)

Description copied from interface: INDArray

Specified by:

get in interface INDArray

Specified by:

get in interface IVector

Specified by:

get in class AVector

dotProduct

public double dotProduct(AVector v)

Description copied from class: AVector

Returns the dot product of this vector with another vector The vectors must have the same length: if not the result is undefined

Overrides:

dotProduct in class AVector

Returns:
