Use of Arma in filter kalman for estimating a curve prosess

The Open Porous Medium (OPM) consortium provides industry-compatible open-source finite-element flow simulation code with robust

输入UTC时间，计算月球在J2000和WGS84坐标系中的位置和速度(Input：UTCtime Output：Position and velocity of moon in J2000 and WGS84)

说明：  引入具有平移不变性和良好的方向分析能力的双树复小波变换对源图像进行多尺度分解;然后对分解得到的各尺度的高频子带采用基于跨尺度的邻域空间频率的融合策略,最高层的低频子带采用基于改进的邻域熵的融合策略进行融合处理;最后对融合后的各个频带进行双树复小波逆变换,重构出融合图像(The dual tree complex wavelet transform with translation invariance and good direction analysis ability is introduced to decompose the source image in multi-scale; then the fusion strategy based on the cross-scale neighborhood space frequency is adopted for the high-frequency subband of each scale obtained by decomposition, and the fusion strategy based on the improved neighborhood entropy is adopted for the low-frequency subband of the highest level; finally, each frequency band after fusion is carried out Double tree complex wavelet inverse transform to reconstruct fusion image)

LTE中pucch的ZC基序列去除相关性(ZC base sequence in LTE pucch removal relevance)

welch 和burg 算法实现功率谱估计(welch and burg algorithm to achieve power spectrum estimation)

该程序模拟了雷达照射区域存在多个点目标，利用线性自回归的方法进行目标估计，包括burg,Yule-Walker法AR 谱估计和修正的协方差谱估计。(The program simulates the radar of the irradiated region there are multiple points of the target, using linear target is estimated from the regression method, including burg, Yule-Walker method AR spectral estimation and the modified covariance spectral estimation.)

在文本文件中嵌入MATLAB代码并运行返回结果 类似在HTML中嵌入PHP和ASP代码，本函数实现在文本文件中嵌入matlab代码并运行！ 主要作用以及价值： 在文本文件中嵌入matlab代码，并可以直接运行该文本文件 根据matlab变量的当前值，实时修改文件文件中相应的数据 目前具有如下功能： matlab代码使用必须包含在< >符号中，中间的内容都被解析为matlab代码 matlab代码可以放在文本的任意位置，你想放在什么地方都可以 matlab代码允许被文本分割而不连续书写，比如循环语句 fprintf(fid_target,...)函数用来向文件中写入字符，目前还比较麻烦 有待改进的方面有： 在文本文件中增加对matlab function的支持 简化变量输出，目前只能fprintf(fid_target,...) 目前是M脚本完成功能的，后期会提供M函数(MATLAB code embedded in the text file and run return results Similar PHP and ASP code embedded in HTML, the function matlab code embedded in the text file and run! A major role as well as the value of: Matlab code embedded in the text file, and can be run directly on the text file Modify the data file file based on the current value of the matlab variables, real-time Currently has the following functions: matlab code uses the symbol in the middle of the parse matlab code must contain matlab code can be placed anywhere in the text, where you want to put matlab code allows text segmentation without the consecutive writing, such as loop statement fprintf (fid_target, ...) function is used to write characters to the file, there is too much trouble Areas for improvement: Increase support for matlab function in a text file Simplify variable output, can only the fprintf (fid_target ...) M script completed, late M function)
