wrap

public static ArraySubVector wrap(double[] data,
                  int offset,
                  int length)

length

public int length()

Specified by:

length in interface IVector

Specified by:

length in class AVector

get

public double get(int i)

Description copied from interface: INDArray

Returns the double value at the specified position in a 1D vector

Specified by:

get in interface INDArray

Specified by:

get in interface IVector

Specified by:

get in class AVector

Returns:

set

public void set(int i,
       double value)

Specified by:

set in interface INDArray

Specified by:

set in interface IVector

Specified by:

set 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

addAt

public void addAt(int i,
         double v)

Overrides:

addAt in class ArrayVector

hashCode

public int hashCode()
