watex.utils.z2rhoa

watex.utils.z2rhoa(z, freq)

Convert impendance tensor z to apparent resistivity

Parameters:

• z (ndarray, shape (N, M)) – Impedance tensor in \(\Omega\)

• freq (array-like , shape (N, )) – Frequency in Hertz

: :return: Apparent resistivity in \(\Omega.m\) :rtype: ndarray, shape (N, M)

Example:

>>> import numpy as np
>>> z = np.array([2 + 1j *3 ])
>>> f = np.array ([1014])
>>> z2rhoa(z, f)
... array([[1623.73691735]])
