MATLAB.7

本书按逻辑编排，自始至终用实例描述；内容完整且每章相对独立；是一本简明的MATLAB参考书，既适用于初学者，也适用于高级MATLAB用户。(This book logically arranged from beginning to end examples describing the content of complete and relatively independent of each chapter it is a simple MATLAB reference books, both for beginners, but also to high-level MATLAB users.)

this program simulates 1D electromagnetic Maxwell equations with absorbing boundary condition to prevent reflection from the boundaries of the problem space. this is by using finite difference time domain method FDTD
