chan算法，利用TDOA参数实现定位功能，是一种很经典的算法(chan algorithm parameters using TDOA positioning function, is a classic algorithm)

说明：  绘制庞加莱截面图,在相空间中适当（要有利于观察系统的运动特征和变化，如截面不能与轨线相切，更不能包含轨线）选取一截面，在此截面上某一对共轭变量如x1和x.1取固定值，称此截面为Poincare截面，相空间的连续轨迹与Poincare截面的交点成为截点。(mapping Poincare section, in phase space appropriate (observation system should be beneficial to the movement and change, if not with the section line tangent track, rail lines not included) selected a cross section, in this section for a pair of conjugate variables such as x1 and X.1 from fixed value, stating that this section of the Poincare section, phase space for the track and Poincare sections of the intersection as intercept point.)

Conduct a digital system ( electronic lock ) using hierarchic methodology . An electronic lock is a device that allows access or opening of a system , as long as the key or combination to enter match with which it is predefined in said lock .

利用Capon, MUSIC进行窄带信号空域信号方向估计。比较分辨率性能。观察阵元数、信噪比、快拍数对估计器性能的影响。 (Using Capon, MUSIC for narrowband signal airspace signal direction estimates. Comparative resolution performance. Observe the number of array elements, signal to noise ratio, the number of snapshots on the estimator performance.)

此算法为用于解反问题的lsqr算法，对Ax=b，输入矩阵A，列向量b，以及迭代步数，求得列向量x(This algorithm is used for solution of the inverse problem lsqr algorithm, Ax = b, the input matrix A, the column vector b, as well as the number of iterative steps, to seek the column vector x)

这个程序是一个提取图像的LBP特征的程序，里面有可执行的m文件，有使用说明。对于一个不是太懂matlab的来说，可以直接拿来使用，附有使用说明。(This program is an extract LBP features of the image of the program executable m file with instructions for use. For a not too understand matlab can be directly used, with instructions for use.)

一个很好的船舶仿真源程序，希望对大家有用。(Simulation of a good source of the ship, in the hope that useful.)

EEMD总体经验模式分解，EMD 的一种改进算法，可用于信号的去噪。(EEMD overall empirical mode decomposition, EMD of an improved algorithm can be used for signal de-noising.)

说明：  实现了无需水平集重新初始化的水平集演化，速度有极大提高(Achieved without re initialize the level set evolution, the speed greatly improved)
