用来实现三维阻抗及光学断层成像重建的matlab程序

function [V] = forward_solver(vtx,E,I,tol,pp,V);

This function solves the forward problem using the Cholesky or LU method or 
conjugate gradients. 



vtx = The vertices
E   = The full rank system matrix 
I   = The currents matrix (RHS) 
pp  = the column permutation vector 
V   = The approximated nodal potential distribution
tol = The tolerance in the forward solution, e.g. 1e-5
