这个说明倒不是说明函数的功能，只是声明一下函数中出现的问题。 shortest()函数没有问题，在secshortest中我希望只得到一条次短路（或几条roadcost()值相同的次短路），结果却出来好几条，我仔细检查了一下程序，应该没有什么问题。 因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。 有些奇怪 (Note that this is not the function of function, but a statement about the problems in function. shortest () function there is no problem, I hope that in secshortest only a short time (or several roadcost () times the value of the same short-circuit), the result is several out, I carefully examined the process, it should be no problem. Therefore, in use, to be at a short circuit can only be used roadcost () function, respectively, for some of the weight of the road and find the smallest. Some strange)

说明：  进行等时延分段，并对等间隔段的两个时延矩阵分别求取均值，采用类似联合近似对角化，估计出最优化的酉矩阵，(ing second-order statistics (different time-delay correlation matrix) of non-stationary and structural characteristics of the signal timing can roughly estimate that the instantaneous linear mixture of blind source signal. With the time delay increasing, only using a single delay covariance equalization and ignoring the time-varying characteristics of the signal, which difficult to ensure the performance of algorithm. Analysis of the average characteristics of ma)

libev-4.15源码 libev是Marc Lehmann用C写的高性能事件循环库。通过libev，可以灵活地把各种事件组织管理起来，如：时钟、io、信号等。libev在业界内也是广受好评，不少项目都采用它来做底层的事件循环。node.js也是其中之一(libev-4.15 source libev Marc Lehmann is written in C, a high-performance event loop library. By libev, the flexibility to manage the organization of various events, such as: clock, io, signals. libev is also widely acclaimed in the industry, many projects have adopted it as the underlying event loop. node.js is one of them)
