simpeg.regularization.Sparse.length_scale_z

property Sparse.length_scale_z

Multiplier constant for smoothness along z relative to base scale length.

Where the \(\Delta h\) defines the base length scale (i.e. minimum cell dimension), and \(\alpha_z\) defines the multiplier constant for first-order smoothness along z, the length-scale is given by:

\[L_z = \bigg ( \frac{\alpha_z}{\Delta h} \bigg )^{1/2}\]

Returns:

float
