- class emg3d.maps.MapLgResistivity[source]#
Bases:
BaseMap
Maps log_10(ρ) to computational variable σ (conductivity).
forward: x = log_10(ρ) = log_10(σ^-1)
backward: σ = ρ^-1 = 10^-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.
