用来实现三维阻抗及光学断层成像重建的matlab程序

function [IntGrad] = integrofgrad(vtx,simp,mat_ref);

function that calculates the integral of the gradients for first order 
tetrahedral elements. Required for the calculation of the Jacobian. 



vtx     = The vertices matrix
simp    = The simplices matrix
mat_ref = The reference conductivity vector
IntGrad = The intgral of the gradients
