我国配电网一般采用中性点非有效接地方式，该配电网通常被称为小电流接地系统。故障选线是长期以来国内外关注的一大难题。提供了一种判别单相接地故障的程序，以及程序所用的数据。数据是EMTP仿真结果。(China' s distribution network is generally used non-effectively grounded neutral manner, often referred to as the distribution Netcom small current grounding system. Fault line is a major concern of long-standing problem at home and abroad. Provides a ground fault identification procedures and procedures used by the data. EMTP simulation results data.)

Defines continuous-time linearised state-space model of Cessna Citation aircraft (slightly modified) as LTI object or as 4 matrices of state-space model.

用于建模数据分集。计算各样本点的欧式距离，首先将距离最大的两个点放入第一个样本集，接着将余下距离最大的两个点放入第二个样本集，依次计算，将剩余数据点分别放入上述两个样本集。( This algorithm starts by selecting the two points furthest from each other (euclidean distance) and puts them both in a first set. Then the next two points furthest from each other are put in a second set, and the procedure is continued by alternatively placing pairs of points in the first or second set. For calibration applications, the second set can be the test set, and the calibration would be the concatenation of the first set plus the remaining samples.)

利用PLSI算法自动对一个文档集进行聚类，需要调节聚类的维度K值，从而得到最大的likelihood(PLSI automatically using an algorithm for clustering document set needs to be adjusted to the dimension value of K clusters, to obtain the maximum likelihood)

卡尔曼滤波在目标跟踪中应用仿真研究。 子函数能完成对运动目标位置的卡尔曼滤波跟踪。 主函数针对一具体假设完成跟踪，并且完成蒙特卡罗仿真。 情景假定：有一两座标雷达对一平面上运动的目标进行观测，目标在 0-600秒沿x轴作恒速直线运动，运动速度为15米/秒，目标的起始点为(-10000米，2000米)。雷达扫描周期T=2秒，x和y独立地进行观测，观测噪声的标准差均为100米。(This program described the Kalman filter algorithm according to a given scenario, simulation achieved the target tracking observation data and Kalman filter results, and the experimental results is studied using the Monte Carlo simulation. )
