In his 1960 famous publication (“A new approach to linear filtering and prediction problems”, Trans.ASME J. Basic Engineering., vol 82, March 1960, pp 34-45), Rudolf Kalman based the construction of the state estimation filter on probability theory, and more specifically, on the properties of conditional Gaussian random variables. The criterion he proposed to minimize is the state vector covariance norm, yielding to the classical recursion : the new state estimate is deduced from the previous estimation by addition of a correction term proportional to the prediction error (or the innovation of the measured signal).

matlab编写的kmeans聚类算法，最后输出每类聚类结果，可自行制定分类数，(kmeans clustering algorithm matlab prepared, the final output of each type of clustering result, the number of self-classification could be developed)

遗传算法 用于 图像处理方面的 matlab源码 请多指教(Genetic algorithms for image processing matlab source please enlighten)

本程序是实现电力系统的故障计算程序，故障后会对导纳矩阵进行修正，很好的进行了仿真(This program is a power system fault calculation program, fault admittance matrix will be revised, a good simulation)

此程序为matlab函数，实现用结构相似性（SSIM）准则评价图像，与峰值性噪比的作用类似。(This program is a matlab function, and criteria for evaluation of structural similarity (SSIM) image acts like a peak-noise ratio.)

T_XTIDE Tidal prediction YOUT=T_XTIDE(STATION) makes a tidal prediction for the current day using the harmonics file XTIDE. Predictions at other times can be generated using [...]=T_XTIDE(STATION,TIM) where TIM is a vector of matlab-format decimal days ( DATENUM). If TIM is a scalar then it is taken as the number of days present over which to make predictions. If TIM>1000 then it is taken to be the starting time in matlab-format. at the matlab time JD (UTC, but see code for details) where tau = lunar time s = mean longitude of the moon h = mean longitude of the sun p = mean longitude of the lunar perigee np = negative of the longitude of the mean ascending node pp = mean longitude of the perihelion (solar perigee)
