说明：  matlab 实现的局部图象增强程序,是自己编的饿(matlab realize local image enhancement procedure is own the hungry)

使用k均值算法对多个数据集进行分类，已测试通过，简单易懂(classification to many datasets using k-means algorithm ,simple and easy-understanding.)

matlab数据处理程序，在处理试验数据时很有用(matlab data processing procedures, the treatment is useful when experimental data)

文件中包含一个地形数据，一个将此数据用matlab进行三维显示的程序。自己写的，可用于航迹规划中的地形测试。(The file contains a terrain data, three-dimensional display this data using matlab program. Write their own terrain test can be used for route planning.)

振动理论中运用单自由度系统的实际例子来列出微分方程并使用ode45进行计算解答(Vibration theory using practical examples to list a single degree of freedom system differential equations and calculations using ode45 answer)

Matlab入门级图像处理程序：利用巴特沃斯（Butterworth）低通滤波器对受噪声干扰的图像进行平滑处理(Matlab entry-level image processing procedures : use Butterworth (Butterworth) low-pass filter to noise interference by the image smoothing)

matlab-使用移位寄存器生成m序列（CDMA系统）(matlab-use shift register to generate m sequence (CDMA systems))

discuss the cooling of a circular fin by means of convective heat transfer along its length. Convection gives rise to a temperature-dependent heat loss or sink term in the governing equation. Shown in Figure 4.9 is a cylindrical fin with uniform crosssectional area A. The base is at a temperature of 100°C (TB) and the end is insulated. The fin is exposed to an ambient temperature of 20°C
