通过一系列教学实例，帮助学生很好的理解matlab中的符号运算实现微分、积分（定积分与不定积分）、极限、级数、绘图等常用功能，几乎可以推导高数中的绝大部分公式，也可用于理论公式推导。(Through a series of teaching examples to help students a good understanding of symbolic computation matlab achieve differentiation, integration (with the definite integral indefinite integral), ultimate, series, graphics and other commonly used functions can be derived almost most of the high number of formulas can also be used to derive theoretical formulas.)

matlab读取电离层电子含量文件，主要是读出格网数据。(matlab read the ionospheric electron content of the document, the main network data is read out of line.)

Binary erosion and dilation, with fast iterative calls. For any structuring element other than square or disk this function is way faster than imerode.m and imdilate.m (more than an order of magnitude). It s also handy when you don t have the Matlab Image Processing Toolbox :-)... It also allows very fast iterative calls (for instance when sweeping the structuring element while looking for a certain effect, threshold in image statistics, etc). See the help in bmorph.m and the attached .pdf file.

说明：  MATLAB基础知识，入门MATLAB很好的课件(MATLAB basics, entry MATLAB good courseware)

这是一个完整实现了模糊聚类的软件包，包中有多个子程序(this is a package of fuzzy clustering algorithm, containing multiple sub-algorithm in it.)

通过matlab仿真分析了LFM信号的数字下变频步骤，包含NCO CIC FIR数字滤波器等模块(The digital down conversion step of the LFM signal is analyzed by matlab simulation, including the NCO CIC FIR digital filter module.)

说明：  本文阐述了扩展频谱通信技术的理论基础和实现方法，利用MATLAB 提供的可视化 工具Simulink 建立了扩频通信系统仿真模型，详细讲述了各模块的设计，并指出了仿真建模 中要注意的问题。在给定仿真条件下，运行了仿真程序，得到了预期的仿真结果。同时，利 用建立的仿真系统，研究了扩频增益与输出端信噪比的关系，结果表明，在相同误码率下， 增大扩频增益，可以提高系统输出端的信噪比，从而提高通信系统的抗干扰能力。 (This paper describes the theory of spread-spectrum communication technology and implementation methods based on the use of visualization tools provided by MATLAB Simulink to establish a spread spectrum communication system simulation model, described in detail the design of each module, and pointed out that the simulation modeling to note problem. In the given simulation conditions, running a simulation program to obtain the desired simulation results. Meanwhile, the use of the simulation system to study the spreading gain and the relationship between the output signal to noise ratio, results show that the same bit error rate, increased spreading gain can increase the system output signal to noise ratio, thereby enhancing communication system disturbance.)
