这是一些关于人脸识别的MATLAB程序，主要对人脸清晰度的处理，可以使图形信息更加的清晰，希望对大家有好的方面(This is some of the MATLAB program on the face recognition, mainly on the treatment of facial definition, can make information more clear graphics, I hope all of you there are good aspects of)

偏微分方程的数值解法的MATLAB程序介绍了应用最为广泛的椭圆型、双曲型、抛物型偏微分方程的数值解法，而且还详细编程实现了每种方程的多种常见数值解法。 附件使用MATLAB编程来实现这些算法。 (The numerical solution of partial differential equations of the MATLAB program, introduced the most widely used elliptic, hyperbolic, parabolic partial differential equations numerical solution, but also details of each program to achieve a variety of common numerical solution of equations. Attachments that use the MATLAB program to implement these algorithms.)

matlab code for slm in the ofdm system .OFDM is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method. A large number of closely spaced orthogonal sub-carrier signals are used to carry data on several parallel data streams or channels.

esprit算法对有干扰的信号频率进行估计,信号处理中的旋转不变子空间法，相控阵天线的方向图（切比雪夫加权）。( esprit algorithm signal frequency interference can be assessed Signal Processing ESPRIT method, Phased array antenna pattern (Chebyshev weights).)

例1 采用动量梯度下降算法训练 BP 网络。 例2 采用贝叶斯正则化算法提高 BP 网络的推广能力。在本例中，我们采用两种训练方法，即 L-M 优化算法（trainlm）和贝叶斯正则化算法（trainbr），用以训练 BP 网络，使其能够拟合某一附加有白噪声的正弦样本数据。(Example 1 uses the momentum gradient descent algorithm to train the BP network. Example 2 uses the Bayesian regularization algorithm to improve the generalization ability of BP network. In this example, we use two training methods, the LM optimization algorithm (trainlm) and the Bayesian regularization algorithm (trainbr), to train the BP network to fit a sine sample with white noise data. )
