- class SimPEG.objective_function.ComboObjectiveFunction(objfcts=None, multipliers=None, **kwargs)[source]#
A composite objective function that consists of multiple objective functions. Objective functions are stored in a list, and multipliers are stored in a parallel list.
is equivalent to
W matrix for the full objective function.
Call self as a function.
First derivative of the composite objective function is the sum of the derivatives of each objective function in the list, weighted by their respective multplier.
deriv2(m[, v, f])
Second derivative of the composite objective function is the sum of the second derivatives of each objective function in the list, weighted by their respective multplier.
Find an objective function type from a ComboObjectiveFunction class.
