说明：  在前面1维FDTD的基础上给出了2维的FDTD程序。可以帮助我们解决比如波导，光纤中的电磁场计算问题。尤其是给出了边界条件的设置方法。(in front of a peacekeeping FDTD given on the basis of two-dimensional FDTD procedures. We can help solve such as waveguides, optical fiber of electromagnetic computation. In particular, given the boundary conditions be set.)

The false position method, Secant method, and Bisection method are term for problem-solving methods in arithmetic, algebra, and calculus. Credit : http://en.wikipedia.org/wiki/False_position_method http://en.wikipedia.org/wiki/Secant_method http://en.wikipedia.org/wiki/Bisection_method

说明：  分为三个函数，第一个函数的功能是用于读取ecg信号，找到小波变换模极大序列；第二个函数是子程序，用于多分辨率分解，使用 A trous 算法在分解的过程中，同时给出各级的细节和概貌，它们和原数据有着同样的长度；第三个函数是函数子程序，用于多分辨率分析中的重建。(Divided into three functions, the function of the first function is used to read the ecg signal, find the wavelet transform modulus maxima sequence second function is a subroutine for use in multi-resolution decomposition, the decomposition algorithm using A' trous process, and gives details of all levels and profiles, they are the original data have the same length third function is a function subprogram, for multi-resolution analysis of the reconstruction.)
