    • getValue

      @Deprecated N getValue(int dimension)
      Deprecated.
      Description copied from interface: FeatureVector
      Returns the value in the specified dimension.
      Specified by:
      getValue in interface FeatureVector<N extends Number>
      Parameters:
      dimension - the desired dimension, where 0 ≤ dimension ≤ this.getDimensionality()-1
      Returns:
      the value in the specified dimension

    • doubleValue

      double doubleValue(int dimension)
      Returns the value in the specified dimension as double. Note: this might seem redundant with respect to getValue(dim).doubleValue(), but usually this is much more efficient due to boxing/unboxing cost.
      Parameters:
      dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()
      Returns:
      the value in the specified dimension

    • floatValue

      float floatValue(int dimension)
      Returns the value in the specified dimension as float. Note: this might seem redundant with respect to getValue(dim).floatValue(), but usually this is much more efficient due to boxing/unboxing cost.
      Parameters:
      dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()
      Returns:
      the value in the specified dimension

    • intValue

      int intValue(int dimension)
      Returns the value in the specified dimension as int. Note: this might seem redundant with respect to getValue(dim).intValue(), but usually this is much more efficient due to boxing/unboxing cost.
      Parameters:
      dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()
      Returns:
      the value in the specified dimension

    • longValue

      long longValue(int dimension)
      Returns the value in the specified dimension as long. Note: this might seem redundant with respect to getValue(dim).longValue(), but usually this is much more efficient due to boxing/unboxing cost.
      Parameters:
      dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()
      Returns:
      the value in the specified dimension

    • shortValue

      short shortValue(int dimension)
      Returns the value in the specified dimension as short. Note: this might seem redundant with respect to getValue(dim).shortValue(), but usually this is much more efficient due to boxing/unboxing cost.
      Parameters:
      dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()
      Returns:
      the value in the specified dimension

    • byteValue

      byte byteValue(int dimension)
      Returns the value in the specified dimension as byte. Note: this might seem redundant with respect to getValue(dim).byteValue(), but usually this is much more efficient due to boxing/unboxing cost.
      Parameters:
      dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()
      Returns:
      the value in the specified dimension

    • getColumnVector

      Vector getColumnVector()
      Returns a Vector representing in one column and getDimensionality() rows the values of this NumberVector of V.
      Returns:
      a Matrix representing in one column and getDimensionality() rows the values of this NumberVector of V
