MapResistivity

class emg3d.maps.MapResistivity

Bases: emg3d.maps.BaseMap

Maps ρ to computational variable σ (conductivity).

• forward: x = ρ = σ^-1

• backward: σ = ρ^-1 = x^-1

Methods Summary

backward(mapped)	Mapping to conductivity.
derivative_chain(gradient, mapped)	Chain rule to map gradient from conductivity to mapping space.
forward(conductivity)	Conductivity to mapping.
