__init__(*args)

getCallsNumber()

Accessor to the number of times the hessian has been called.

Returns:

calls_numberint

Integer that counts the number of times the hessian has been called since its creation.

getClassName()

Accessor to the object’s name.

Returns:

class_namestr

The object class name (object.__class__.__name__).

getInputDimension()

Accessor to the number of the inputs.

Returns:

number_inputsint

Number of inputs.

getMarginal(*args)

Accessor to the hessian implementation of a specific output.

Parameters:

iint

Integer corresponding to the output (Care: it starts at 0).

indicessequence of integer

The set of indices for which the outputs are extracted.

Returns:

hessianImplementationHessianImplementation

A hessian implementation restricted to its compenents functions which indices are i or indices.
