多项式和非多项式曲线拟合

说明：  利用温度变送器模拟量输入，控制电动阀的开度，从而调节水泵流量。(Using the analog input of temperature transmitter, the opening of the electric valve is controlled to regulate the flow rate of the pump)

说明：  可以判断数据的实时性，处理数据的格式，将gis、dat数据转换成xls或科傻in1数据，并且自动添加转点(It can judge the real-time of data, process the format of data, convert GIS and dat data into XLS or kesain1 data, and automatically add transfer points)

说明：  主成分分析(PCA)是多元统计分析中用来分析数据的一种方法,它是用一种较少数量的特征对样本进行描述以达到降低特征空间维数的方法,(Principal Component Analysis (PCA) is a method used to analyze data in multivariate statistical analysis. It uses a small number of features to describe samples in order to reduce the dimension of feature space.)

说明：  This simulation code package is mainly used to reproduce the results of the following paper [1]: [1] Linglong Dai, Bichai Wang, Mugen Peng, and Shanzhi Chen, “Hybrid Precoding-Based Millimeter-Wave Massive MIMO-NOMA with Simultaneous Wireless Information and Power Transfer,”to appear in IEEE Journal on Selected Areas in Communications, 2018.(Non-orthogonal multiple access (NOMA) has been recently considered in millimeter-wave (mmWave) massive MIMO systems to further enhance the spectrum efficiency.)
