# SimPEG.simulation.LinearSimulation#

class SimPEG.simulation.LinearSimulation(mesh=None, linear_model=None, model_map=None, G=None, **kwargs)[source]#

Class for a linear simulation of the form

$d = Gm$

where $$d$$ is a vector of the data, G is the simulation matrix and $$m$$ is the model. Inherit this class to build a linear simulation.

Attributes

 linear_model The model for a linear problem physical property model. model_deriv Derivative of The model for a linear problem wrt the model. model_map Mapping of the inversion model to The model for a linear problem.

Methods

 Jtvec(m, v[, f]) Jtv = Jtvec(m, v, f=None) Effect of transpose of J(m) on a vector v. Jvec(m, v[, f]) Jv = Jvec(m, v, f=None) Effect of J(m) on a vector v. dpred(m[, f]) Create the projected data from a model. u = fields(m) The field given the model.
