Description copied from interface: FeatureVector

Returns the value in the specified dimension.

Specified by:

getValue in interface FeatureVector<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
