this is the matlab programming to determine or analyze inrush current with variable voltage value

电源系统常用的电压控制仿真系统，研究人员必备佳品。(Power system voltage control simulation system used, the researchers required to share.)

基于SVR的线性系统的辨识和校验，辨识信号采用幅值为2的随机信号(Linear systems based on SVR identification and validation, identification signal using random signal amplitude of 2)

This is a simple position location algorithm using Least Square Estimation algorithm. Timing information is time of flight (TOA) of signal between Tx and Rx. This code generally describes the Positioning method, Also it plots final coordinate of node in 2D. All other information was inlcuded as comments in source code.

说明：  基于DCT的水印图像matlab代码，主要是水印嵌入和水印提取两大主要部分(DCT-based image watermarking matlab code, mainly watermark embedding and watermark extraction are two main parts)

说明：  数值算法积分运算，可以将一组数据方程化后积分求解(quad in matlab)

matlab下进行可将logo加到照片上(matlab under the logo can be added to the photo)

游需求分析婶予促进我目各地区的经济发展和文化交流都有着重要的意叉。由于旅游行业的。小样本，膏信息，不确定”性， 旅游市场可以看做是一个巨大的灰色系统。皋文竹对旅游需求同题进行了详细的研完，提出了基于灰色表镜理论的多元数学预测模型GM (1，N)．合理分析诸多因素对旅游需求的综合影响，可以很好的解决此奏问题。同时。以北京地区旅游需求发展为倒，根据北京市旅游局平 的历年旅游统计数据，确定影响游客人数的因素并对其合理量化，应用GM(1，N)模型对最地的旅游需求进行预潮．井通过残盖检验，后戎 差检验手方法对谊模型进行分析．得到的攮测结晨比较准磅，未模型应用范田广泛，可以进行推广使用。(Travel demand analysis aunt I promote my head the region s economic development and cultural exchange has an important meaning fork. As the tourism industry. Small sample, paste the information, uncertain "sex, Tourism market can be seen as a huge gray system. Gao asparagus tourism demand with the title for a detailed study finished, put forward the theory based on gray table mirror multivariate mathematical prediction model GM (1, N). Rational analysis of factors combined effects of tourism demand, can solve this problem outs. Simultaneously. Development of regional tourism demand in Beijing is an inverted, according to the Beijing Municipal Tourism Bureau level Calendar year tourism statistics to determine the factors that affect the number of visitors and their reasonably quantified, the application of GM (1, N) model of the tourism demand for the most pre-cuts. Well residue cover through test after Rong Poor test methods friendship hand model for analysis. Nang get more accurat)

基于矩阵重构的DOA估计算法，包含DSVD算法和ESVD算法(The DOA estimation algorithm including DSVD and ESVD)
