MapLnResistivity

class emg3d.maps.MapLnResistivity

Bases: emg3d.maps._Map

Maps log_e(ρ) to computational variable σ (conductivity).

• forward: x = log_e(ρ) = log_e(σ^-1)
• backward: σ = ρ^-1 = exp(x^-1)

Methods Summary

backward(mapped)	Mapping to conductivity.
derivative(gradient, conductivity)	Map derivative from conductivity back to mapping space.
forward(conductivity)	Conductivity to mapping.
