多通道经验模态分解，程序加实例分析，适合初学者(Multivariate Empirical Mode Decomposition (MEMD) code)

emd改进算法，克服了emd算法的模态混叠，屏蔽经验模态分解算法。(The Improved EMD algorithm overcomes the modal aliasing of EMD algorithm and shields the empirical mode decomposition algorithm.)

多元经验模式分解（MEMD）算法是EMD算法从单个变量到任意数量的变量的扩展，其与经验模态分解一样存在模式混合问题，基于噪声辅助的多元经验模式分解（NAMEMD）就在对MEMD的改进，解决其问题。(The multiple empirical mode decomposition (MEMD) algorithm is an extension of the EMD algorithm from a single variable to any number of variables. Like
