function [voltageH,voltageV,indH,indV,df]=get_3d_meas(elec,vtx,V,Ib,no_pl);

This function extracts multiplane voltage measurements from a calculated 3D nodal potential 
distribution V inside a tank with (no_pl) electrode planes. Each plane holds the same number 
of electrodes. Only the non-current carring electrodes at the time are involved in the measurements.



elec      = The electrodes matrix
vtx       = The vertices
V         = The calculated forward solution
Ib        = The current patterns without the zeroes patch
no_pl     = The number of planes

voltage_H = Horrisontal (local plane) measurements
indH      = The two column matrix indicating the indices of the electrodes 
            involved in voltage_H, e.g. indH = [2 3; 3 4; 4 5;...] implies 
            voltage_H(1) = voltage(2) - volatge(3), etc
df        = Array indexing the (numbero of) measurements to their corresponding 
     current patterns. 
voltage_V = Vertical interplanar measurements
indV      = ...
