N-way_Toolbox

this code implements a curvelet toolbox

说话人识别demo。matlab代码，自己看吧。(Speaker recognition demo. matlab code, and see themselves.)

说明：  popfnn神经网络，它是一种模糊伪输出的神经网络(pseudo-outer-production fuzzy nerual network).可用于模式识别。运行pop1可以训练输入的特征向量，extractionpop使用来抽取图片的特征向量的。(popfnn neural network, it is a pseudo-output fuzzy neural network (pseudo-outer-production fuzzy nerual network). can be used for pattern recognition. Can be trained to run pop1 input feature vector, extractionpop used to extract the image feature vector.)

利用白噪声序列和传递函数生成有色噪声的源代码，很实用(Using white noise sequence and colored noise transfer function to generate source code, very useful)

线天线阵和面天线阵在MATLAB内的方向图以及半功率带宽(Antenna array and antenna array within the orientation map in MATLAB and the half-power bandwidth of)

说明：  直线偏移代码，已知多边形顶点坐标，可以将多边形各边沿其法线方向平移距离然后得到新的多边形顶点。(Linear shift code, known polygon vertex coordinates, can be the edge of the polygon shift its normal direction and then get a new polygon from the vertex.)

使用卡尔曼滤波器设计的运动物体跟踪。适用于背景也是动态变化的物体跟踪(Tracking moving objects using a Kalman filter design. Applies to the background also dynamic object tracking)

说明：  与连续信号的解调相比，短时突发信号持续时间短，不适用性能良好的反馈环路算法，需要使用前向幵环算法。与一般突发信号相比，短时突发信号没有训练序列、同步头等辅助信息，所有参数需要利用有限的数据估计。与合作通信相比，盲接收信号参数的初始偏差较大，估计范围小的算法不适用。每个突发包的数据有限，解调过程不允许丢失任何符号。(Compared with the demodulation of continuous signal, short burst signal has a shorter duration and is not suitable for the feedback loop algorithm with good performance. Forward loop algorithm is needed.)

根据样本估计密度曲线的方法，也就是pavzen窗函数法，采用正态窗函数，先画直方图，在估计平滑的密度曲线(Estimated based on the sample density curve method, which is pavzen window function method, using normal windows function, the first histogram drawn in the estimated density curve smoothing)

基于MATLAB的无标度网络仿真，对于学习复杂网络很很好的启迪(MATLAB-based simulation of scale-free network, complex network is very good for learning inspired)
