一个50行的Matlab有限元程序（二维传热问题），执行fem2d.m即可。(A 50-line Matlab finite element program (two-dimensional heat transfer problem), the Executive fem2d.m can.)

本书由基础知识和应用两大部分组成，基础知识详细介绍了MATLAB基础准备与入门、MATLAB的基本使用方法、数组和数组运算、字符串单元数组和结构、数值计算功能、符号运算、数据和函数的可视化、MATLAB程序设计、图形用户界面设计、Simulink仿真基础；在应用方面，介绍了MATLAB在信号与系统、数字信号处理和通信原理中的应用等内容。本书在介绍方式上使用了大量图片、例子，具有较好的操作指导作用，通过实例帮助读者加深理解。(Benshu basic knowledge and applied by the two major components, introduces the basics of preparation and entry based on MATLAB, MATLAB s basic use, arrays and array operations, array of string units and structures, numerical calculations, symbolic computation, data, and visual function, MATLAB programming, graphical user interface design, Simulink based simulation In the application, describes a MATLAB in signal and systems, digital signal processing and communication theory in the application of content. This book describes the way in the use of a large number of pictures, examples, and has good operating guide, an example to help readers better understanding.)
