Gabor filter with 2 files, creategabor is the function agreeing with the gabor function, gabor is an sample for implementing and visualizing the gabor filter by 5*8 images

说明：  通过在MATLAB平台上比较BP神经网络的三种训练方法－trainbr traingdm trainlm.并且网络中加入噪音！(through MATLAB platform comparison BP neural network training method for the three-trainbr traingdm trainlm. Network and add noise!)

由于飞机设计是一个需要多次反复迭代的重复过程，需要进行大量的计算，因此我们自己编写了一些MATLAB程序。如果您想要查看程序源代码，可以点击下面的链接。 [program_1.m]全机总体参数计算程序 [program_2.m]全机气动曲线计算程序 [program_3.m]机翼载荷分布计算程序 [program_4.m]巡航状态纵向动稳定性计算程序 [program_5.m]横航向稳定性计算程序 [program_6.rar]平飞速度范围计算程序 [program_7.rar]螺旋桨特性计算程序 (The plane design is a requiring multiple iterative repeat process, need to do a lot of calculation, so we can write some MATLAB.)

The m-file contends the matlab code for the class of linkedlist, a classic kind of data structure. OOP is an important and brandnew characteristic of the matlab language, which is embodied in the m-file.

寻找测试样本的最近邻，可以有效的用于用于模式识别，信号处理(This is a small but efficient tool to perform K-nearest neighbor search, which has wide Science and Engineering applications, such as pattern recognition, data mining and signal processing. The code was initially implemented through vectorization. After discussions with John D Errico, I realized that my algorithm will suffer numerical accurancy problem for data with large values. Then, after trying several approaches, I found simple loops with JIT acceleration is the most efficient solution. Now, the performance of the code is comparable with kd-tree even the latter is coded in a mex file. The code is very simple, hence is also suitable for beginner to learn knn search.)

讲了复杂网络的数学建模的理论和建模的方法。(The ppt prensents theory on statistical Mechanics of complex network. It is helpful to establish network models.)
