8阵元均匀线阵方向图

基于小波分析和主成分分析的人脸识别研究随着社会的发展，社会各个方面对快速有效的身份验证的要求日益迫切。由 于生物特征是人的内在属性，具有很强的自身稳定性和个体差异性，因此是身份 验证的理想依据。其中利用人脸特征又是最自然直接的手段，相比其他生物特征， 它具有直接、友好、方便的特点，易于为用户接受。从而，人脸识别吸引了越来 越多来自计算机视觉和信号处理等领域的关注，成为模式识别、图像处理等学科 的研究热点。(Based on wavelet analysis and principal component analysis of the Face Recognition With the social development of all aspects of society in his capacity as quickly and efficiently verify the requirements of increasingly urgent. Biological characteristics as a result of the inherent human attribute, has a strong individual differences in their stability and, therefore, is an ideal basis for authentication. The use of facial features which is the most natural means of direct, compared with other biological characteristics, it has a direct, friendly, convenient and easy for users to accept. Thus, face recognition has attracted more and more from the computer vision and signal processing and other areas of concern, as a pattern recognition, image processing, such as the research subjects.)

一个激光slam的matlab仿真程序，代码有解释，对学习slam很有帮助(A matlab simulation program for laser slam with explanatory code is very helpful for learning slam.)

用遗传算法求取函数的最大值。遗传算法的每一步骤都用子函数的形式给出。适合对遗传算法的入门级选手学习、参考。(Using genetic algorithms to strike a function of the maximum. Each step of the genetic algorithm is given in the form of a subfunction. Suitable for entry-level players genetic algorithm learning, reference.)

说明：  matlab实现的根据本原多项式生成m序列方法(matlab implementation is based on primitive polynomial generating m-Series Method)

说明：  求根MUSIC算法，仿真中使用的阵列为均匀阵列，阵列数为8，接收信号数为2个，噪声为高斯白噪声。此算法是对经典MUSIC算法的改进，估计精确度更高。(Root MUSIC algorithm, the use of simulation for the uniform array of arrays, arrays of 8 to receive the signal number 2, noise is Gaussian white noise. This algorithm is the classical MUSIC algorithm, it is estimated that a higher accuracy.)

给出了矩形域上分形插值数学模型,分形插值曲面的MATLAB程序,对程序中的主要变量进行了说明,并应用实际数据进行了分形插值曲面的实例研究。运用少量已知数据值,模拟出粗糙表面,这对于直观显示复杂物体的几何形态,研究具有分形特征的地形地貌、断层表面和材料裂隙表面,具有重要的理论意义和实用价值。 更多还原 (Gives the fractal interpolation on a rectangular field mathematical model of fractal interpolation MATLAB program, the main variables of the program are described and applied case studies actual data fractal interpolation surface. Use a small amount of known data values ​ ​ to simulate the rough surface, which visually displays the geometry of complex objects, study topography fractal characteristics, surface faults and fissures surface material has important theoretical and practical value.
