removevolt.m

MATLAB二维电阻抗断层成像算法!用于医学成像,里面包括有限元剖分正问题,及反问题的算法.并且附有网络剖分数据表!

function Vh=RemoveVolt(Uel,L);

%RemoveVolt Removes all the voltages measured on the current carrying electrodes
% Function Vh=RemoveVolt(Uel,L);
% removes all the voltages measured on the current carrying electrodes.
% Change the Jacobian accordingly, see RemoveJacob.m.
%
% INPUT
% Uel = voltages on the electrodes
% L = number of electrodes
% 
% OUTPUT
% Vh = new voltages
