基于MATLAB平台上，计算HU矩的算法编程。可以不用花时间去考程序源代码和下载链接。 (MATLAB-based platform, the calculation of moments algorithm HU programming. Can not take the time to take a program source code and download link.)

应用交替方向乘子法来求解L1正则化问题、BP问题、LASSO问题的一种算法，(Application alternating direction multiplier method to solve L1 regularization problem, BP issue LASSO problem an algorithm)

简单方便的最小二乘法曲线拟合，运用一个实例程序很好的解释了曲线拟合方法(Simple and convenient method of least squares curve fitting, using a good explanation of the example program of curve fitting method)

利用matlab里面的吹风机数据，用前300个数据进行辨识。分别采用最小二乘辨识和相关性系数法辨识。并画出图形。通过对比最小二乘法和相关函数两种方法得出来的辨识图形。可知相关函数辨识的准确度更高。(Use a hair dryer inside matlab data before using 300 data identification. Were used to identify the least squares identification and correlation coefficient method. And draw graphics. By comparing the least squares method and related functions have two ways out of the identification graphics. Shows a higher correlation function identification accuracy.)
