MapLnResistivity
[source]¶ Bases:
emg3d.maps.BaseMap
Maps log_e(ρ) to computational variable σ (conductivity).
forward: x = log_e(ρ) = log_e(σ^-1)
backward: σ = ρ^-1 = exp(-x)
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.
