数字信号处理的MATLAB实现源代码 介绍了滤波器、功率谱等(Digital signal processing in MATLAB source code filters, power spectrum)

本程序的功能是实现人为框定目标后，对目标进行灰度边缘的提取和标记。(gray scale image,edge detected.)

FDTD方法，以PML为边界条件，是二维的算法(FDTD method, the PML boundary condition is two-dimensional algorithm)

u取不同值时CCDF曲线比较，u律压缩扩张法，效果一般(u for different values of CCDF curves, u law compression expansion method, the general effect)

The Scale-Invariant Feature Transform (SIFT) bundles a feature detector and a feature descriptor. The detector extracts from an image a number of frames (attributed regions) in a way which is consistent with (some) variations of the illumination, viewpoint and other viewing conditions. The descriptor associates to the regions a signature which identifies their appearance compactly and robustly

以两个麦克风线性阵列为例通过相关函数进行音源定位，定位范围为0到180度(Case of two microphone linear array sound source through the relevant function location, location range from 0 to 180 degrees)

模特综合法作为一种简化动力学系统的方法，在大型结构动力学分析中有广泛的应用。 文中采用理论推到，AYSYS仿真和matlab编程三种不同分析方法对悬臂板进行了模态分析，并且给出了用到的所有源代码（APDL和m文件）。(Component Mode Synthesis)

形成14节点的电力系统节点导纳矩阵，其中包含程序运行时所用到的关于网络的参数表，程序有详细的注释(Forming a 14-node system node admittance matrix of power, which includes the use of the program is running on the network parameter table, the program has detailed notes)

MATLAB编程源码，可以显示一灰度图像的8个位面图像——bawei.m(MATLAB programming source code, you can display a gray image of the 8-bit plane image- bawei. M)
