FieldUnivariateDerivative

public FieldUnivariateDerivative()

Method Detail

getFreeParameters

public int getFreeParameters()

Get the number of free parameters.

Specified by:

getFreeParameters in interface FieldDerivative<S extends RealFieldElement<S>,T extends FieldUnivariateDerivative<S,T>>

Returns:

number of free parameters

getPartialDerivative

public S getPartialDerivative(int... orders)
                       throws MathIllegalArgumentException

Get a partial derivative.

Specified by:

getPartialDerivative in interface FieldDerivative<S extends RealFieldElement<S>,T extends FieldUnivariateDerivative<S,T>>

Parameters:

orders - derivation orders with respect to each variable (if all orders are 0, the value is returned)

Returns:

partial derivative

Throws:

MathIllegalArgumentException - if the numbers of variables does not match the instance

See Also:

FieldDerivative.getValue()

getDerivative

public abstract S getDerivative(int n)
                         throws MathIllegalArgumentException

Get a derivative from the univariate derivative.

Parameters:

n - derivation order (must be between 0 and FieldDerivative.getOrder(), both inclusive)

Returns:

n^th derivative

Throws:

MathIllegalArgumentException - if n is either negative or strictly larger than FieldDerivative.getOrder()

toDerivativeStructure

public abstract FieldDerivativeStructure<S> toDerivativeStructure()

Convert the instance to a DerivativeStructure.

Returns:

derivative structure with same value and derivative as the instance
