fitbenchmarking.jacobian.best_available_jacobian module

Module which acts as a analytic Jacobian calculator when available, otherwise uses a trusted software to approximate.

class fitbenchmarking.jacobian.best_available_jacobian.BestAvailable(problem)

Class to apply an analytical Jacobian if available – otherwise choose a scipy one.

eval(params, **kwargs)

Evaluates Jacobian of the model, \(\nabla_p f(x,p)\), at the point given by the parameters.

Parameters:: params (list) – The parameter values at which to evaluate the Jacobian
Returns:: Computed Jacobian
Return type:: numpy array

property method

Utility function to get the numerical method

name() → str

Get a name for the current status of the jacobian.
