说明：  协同网络中继选择算法 一种是基于门限的最大信噪比选择；另一种是基于门限的最小误码率选择，我们将选择一条最佳的中继链路和源节点到目的节点的直接传输链路在目的端进行最大比合并(Research on relay selection algorithm in cooperative wireless Networks)

EasyEnsemble和BalanceCascade是两类不平衡数据集的学习方法(EasyEnsemble and BalanceCascade are two class-imbalance learning methods. They can adaptively exploit the majority class examples, avoiding important majority class examples to be ignored by common under-sampling while maintaining the fast training speed of under-sampling. )

Daubechies discrete wavelet transform

HHT谱计算程序，不是rilling版本，用改进的Hilbert变换，效果好一些，供大家参考。(HHT spectrum of the calculation procedures, rilling is not a version of the Hilbert transform used to improve the results better for your reference.)

一个量化噪声分析程序。该代码是不长，只供参考。学生专用的试验。(One of the quantization noise analysis program. The code is not long for reference only. Students of special test.)

两种方法实现图像任意角度旋转，原图像的每个像素点寻找在新图的位置，新图中的每个像素点寻找原图中的位置(Two methods for image rotation of an arbitrary angle, each pixel of the original image at the position to find the new graph, the new image for each pixel to find the original position)

控制数学问题的MATLAB求解，包括：微积分与积分变换问题求解，线性代数、积分方程和差分方程求解(Solution for Control Mathematics Problem )

图像水平变换：分别实现对图像的水平外凹和水平外凸。(Image level of transformation: the implementation level of the image and level .)

说明：  计算平面九桁架的时域动力响应，运用中心差分方法，状态空间法(Nine of plane truss dynamic response in time domain using the central difference method, state space method)

说明：  数字下变频器的matlab实现，一定的设计指标，可以用来知道vhdl程序设计(Digital Down Converter for matlab realized, certain design specifications that can be used to know VHDL Programming)
