this helps for understanding insar simulation

说明：  首先介绍计算机仿真技术和仿真建模方法的基本概念，以便对建模和仿真有个初步和整体的认识；然后对 Simulink 进行简单介绍，并以一个简单例子进行引导；最后介绍 Simulink的工作原理，为后续的深入掌握 Simulink 打下基础。(First introduces the computer simulation technology and the basic concepts of simulation modeling methods, modeling and simulation in order to have a preliminary and general understanding and then a brief introduction to the Simulink and be guided by a simple example Finally, the working principle of Simulink, Simulink for subsequent understanding of the basis.)

说明：  用于线性图形插值放大,需要放置一张图片。可参看代码内加载内容!(Bilinear inter picture which can be used to change a small size picture to a big size picture.)
