public interface IOperator

Interface for a scalar operator that transforms a double value to another double value

Method Summary

Modifier and Type	Method and Description
double	apply(double x) Applies this operator to a single value, returning the result
void	applyTo(AVector v) Applies this operator to a mutable vector.
void	applyTo(AVector v, int start, int length) Applies this operator to the specified range within a mutable vector.
void	applyTo(double[] data, int start, int length) Applies this operator to the specified range within a double[] array.
void	applyTo(double[] data, int start, int stride, int length) Applies this operator to the specified strided range within a double[] array.
Op	getInverse() Gets the inverse of this operator.
ATransform	getTransform(int dims) Converts an operator into a corresponding transform that applies the operator to all elements of its input

Method Detail

apply

double apply(double x)

Applies this operator to a single value, returning the result

Parameters:

x -

Returns:

applyTo

void applyTo(AVector v)

Applies this operator to a mutable vector.

Parameters:

x -

applyTo

void applyTo(AVector v,
             int start,
             int length)

Applies this operator to the specified range within a mutable vector.

Parameters:

x -

applyTo

void applyTo(double[] data,
             int start,
             int length)

Applies this operator to the specified range within a double[] array.

Parameters:

x -

applyTo

void applyTo(double[] data,
