数值分析中经典的arnoldi算法，用来求解大型矩阵方程组的求解(numerical analysis classic arnoldi algorithm used to solve large matrix equations Solution)

说明：  Today’s wireless networks are characterized by a fi xed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15 to 85 with a high variance in time. The limited available spectrum and the ineffi ciency in the spectrum usage neces- sitate a new communication paradigm to exploit the existing wireless spectrum opportunistically

以梯度投影法迭代直接求解出观测值的改正数，给出一个简单算例，以资验证。 (The correction of the observation is obtained by the interation with gradient projection method and a simple calculation example is given to verify it)

基于matlab的SOFC的建模,用simulink的自带模块进行建模(modeling of SOFC)

arma模型的时频归并的matlab实现(arma model achieved when the frequency of incorporation of the matlab)

说明：  本程序是基于方向优先权的机器人最优路径寻找算法，也可用于求解迷宫的最短路径,算法中是以100*100的格点为实例的，其中标0的位置为可行的点，标1的为障碍物，参考者可以根据自己的情况修改场地信息矩阵和起始点、目标点中间的算法不用修改 (This procedure is based on the priority direction of the robot to find the optimal path algorithm can also be used to solve the maze of the shortest path algorithm is 100* 100 grid points for the instance, which marked the location of 0 points as possible, standard 1 for the barrier, reference conditions can modify the site according to their own information matrix and the starting point, target points do not modify the middle of the algorithm)

Real time optical flow, and video processing, with support for camera input in Matlab.(Start by running "runMe.m" Supports input through: a) synthetically generated test images b) reading avi-file c) camera input (requires image aquisition toolbox) Calculates optical flow by 4 different local methods(all moment based), 2 implementations of Lucas and Kanade, and 2 implementations of point-line flow. Can process easily hundreds of frames per second on a laptop for resolution 200x200 images.)

短时傅里叶变换可以用差分模式来实现，对书上的运算式做了稍许的改变。改变-计算差分序列的第一列数据时用的是第一列的元素减去当前行的最后一列元素。原算法中采用的是第一列元素减去下一行第二列元素。原算法加窗之后结果比较好，不加窗时结果误差很大，而改变之后的算法不加窗效果依然很好。(Short time Fourier transform can be used to achieve the differential mode of expression on the book made a slight change. Change- calculating the difference sequence of the data with the first column is the first column of the matrix by subtracting the current element in the last column of row. Is used in the original algorithm subtracts the elements of the first column of the next row and the second column elements. After the results of the original algorithm windowed better, when the results window without great error, and after changing algorithms no window effect is still very good.)
