层次分析法（AHP）是进行评估的一种常用方法，其中层次分析法中求随机一致性指标是该方法的关键一步。本程序即实现的求解PI的程序(AHP is a common method of assessment, in which AHP seek random consistency index is a key step in the method. This procedure that is implemented procedures for solving PI)

fir带通滤波器,可将不需要的频率成分的信号滤去(fir bandpass filter unwanted frequency components can be filtered signal)

此算法是基于matlab的MFCC特征提取算法，其中包括了分帧、归一化等步骤和代码，非常好用，结果是24维的向量(This algorithm is based on MFCC feature extraction algorithm matlab, including the framing, normalization and other steps and code, very easy to use, the result is 24-dimensional vector)

实现主动毫米波异物检测及分割，内部附有论文，及参照论文的实现代码(To achieve active millimeter wave foreign body detection and segmentation, with papers inside, and reference to the implementation of the code)

该代码采用matlab和C混合编写，是采用随机梯度的方法训练线性分类器，它可用于数据、图像等的多类分类情况。参考论文：Good Practice in Large-Scale Learning for Image Classification(This a Stochastic Gradient Descent algorithm used to train linear multiclass classifiers. It is biased towards large classification problems (many classes, many examples, high dimensional data).)

waveguide dispersion simulation

Finite Element solution of Poisson equation

图像反转/灰度线性变换/非线性变换/直方图均衡化,源代码.(Image reversal/gray linear transformation and nonlinear transform and histogram equalization, the source code)

以最优的窗宽进行核密度估计，误差小，比matlab自带程序精确(To the best window width nuclear density estimation, a small error, accurate than matlab own procedures)

说明：  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，因此我自己编写了一些MATLAB程序(As the aircraft design is a need to repeat many times iterative process, requiring a large number of calculations, so I wrote some MATLAB program)
