这是一个求一图像的阀值N取各值所对应的水平线的叠加 ，即水平集的源代码(This is an image for a threshold N check the value of the corresponding horizontal stacking, that is the source code level set)

1.对染噪doppler信号进行小波包3层分解：分解层次j=1,2时，都是信号的概貌；当j=3时，反映概貌的已几乎不含噪声分量，而其它噪声分量的幅值已很小。 2.对加噪Blocks信号进行不同阈值及不同阈值的使用方式降噪。 (1. On noise pollution doppler signal decomposition of wavelet packet Layer 3: decomposition level j = 1,2, are the signal profiles when j = 3 to reflect the general picture has been almost non-noise component, while other noise components amplitude has been very small. 2. Blocks of noise signals of different thresholds and different thresholds for the use of noise reduction methods.)

说明：  本程序是求解一厚壁圆筒的matlab程序，采用平面等参单元计算(This program is a thick-walled cylinder matlab solving procedure for the calculation of plane isoparametric element)

适用于matlab用打靶法解决有边界问题的微分方程，各种参数已经在程序中说明清楚了(shooting method)

空间平滑算法的作用是估计源数目，特别的是可以估计相干源个数(space smoothing technology,and estimate the number of correlation sources.)

把电源系统表示成线性传递函数或非线性控制模型，以此建立一种符号仿真模型(The power system transfer function expressed as a linear or nonlinear control model, in order to establish a symbolic simulation model)

空间普估计之mvm算法 此算法是music算法的改进算法(S & P estimates mvm space algorithm This algorithm is music algorithm improved algorithm)

This is a MATLAB implementation of the SIFT keypoint detector and descriptor (do_gaussian: generate Gaussian scale space of input image do_diffofg: generate Difference of Gaussian (DoG) scale space do_localmax: local extrema as the potential keypoints do_extrefine: refine the keypoints by discarding the ones with low contrast and along an edge do_orientation: compute the orientation of a support region of keypoint do_descriptor: compute the descriptor of a keypoint based on image gradients. do_match: match two images based on the nearest neighbor principle and spatial consistency. do_sift: generate the SIFT descriptors for a given input image. It basically s all the functions above. )

说明：  双融水箱模糊控制，matlab实现，详细(Double melt water tank fuzzy control, matlab implementation, detailed)

采用了一种简化的方向图模型。方位和俯仰均用高斯型。(Direction using a simplified graph model. Azimuth and elevation are used Gaussian.)
