说明：  利用时域有限差分（FDTD）仿真三维（3D）电磁波的传播，吸收边界条件为完全匹配层（PML）。(The use of finite difference time domain (FDTD) simulation of three-dimensional (3D) electromagnetic wave transmission, absorbing boundary condition for the perfectly matched layer (PML).)

function [x, hist] = secant(x, f, tola, tolr) SECANT This a secant code with no line search. This code terminates on small relative-absolute errors function [X, HIST] = SECANT(X, F, TOLA, TOLR) Inputs: X = initial iterate F = function TOLA = absolute error tolerance TOLR = relative error tolerance Output: X = approximate result

给出了三个m文件，分别适用于不同的Shortestpath问题，本程序是工程CT的一部分，属于正演算法，可获得射线路径。每一条均有注释，适合初学者。完美运行。(For the Shortpath, given 3 m files. They are the part of CT for induction. Fit for green hands.)
