中文说明：利用最小二乘法进行拟合多元非线性方程，验证可用，计算多重分形非趋势波动分析，供做算法研究人员参考，脉冲响应的相关分析算法并检验，真的是一个好程序。
English Description：
Using least squares fitting multivariate nonlinear equations and can be used to verify and calculating the multifractal detrended fluctuation analysis, for our algorithm researchers can make a reference to, the impulse response correlation analysis algorithm and test, really is a good program.
