在ar人脸库上实现Direct Fisher discriminant analysis,该方法首先对类内散布矩阵对角化，然后对类间散布矩阵对角化，使类间散布矩阵对角化的矩阵即使鉴别向量集(In the ar face database to achieve Direct Fisher discriminant analysis, this method first within-class scatter matrix diagonalization, and then between-class scatter matrix diagonalization, so that between-class scatter matrix diagonalization of the matrix even if the identification of a vector set)

说明：  matlab编程实例一百个，非常有用的小程序，尤其是在图像处理方面。(matlab programming examples hundred, a very useful little program, especially in image processing.)

该例程内容丰富，包括从基本的bpsk,qpsk,qam到实际的ofdm系统，cdma链路，mac层仿真分析，对OFDM信道建模，包括普通IDFT算法和IFFT快速算法，基于OFDM体制的调制和解调程序，降低OFDM系统PAPR的pts算法的仿真程序，完整的OFDM链路程序并作了较为具体的解析(The routines cover a wide range from basic bpsk, qpsk, qam to the actual ofdm systems, cdma link, mac layer simulation, the OFDM channel modeling, including ordinary IDFT algorithm and IFFT fast algorithm, based on OFDM modulation system and demodulation process, reduce the PAPR of OFDM system pts algorithm simulation program, a complete OFDM link process and made more specific analysis)

机械优化设计主要包括建立优化设计问题的数学模型和选择合适的优化方法及程序两方面的内容.基于二次插值法的基本原理,通过实例,编写MATLAB程序进行求解,计算结果说明了二次插值法是一种求解一元函数极小点问题最优解的可行高效的方法.(Mechanical optimization design includes a mathematical model to optimize the design of the problem and choose the appropriate two aspects of optimization methods and procedures based on the basic principles of quadratic interpolation method, is solved by way of example, the preparation of MATLAB, the results illustrate the quadratic interpolation method is a function of one yuan to solve the problem of the optimal solution of the minimum point efficient way possible.)

这是雷达成像中的一个简单的成像算法-RD算法，这个算法能很好的成像，而且成像质量也不错(This is the radar imaging of a simple algorithm-RD imaging algorithm, this algorithm can be very good imaging, and image quality is also good)
