VMD(Variational Mode Decomposition)是一种信号分解方法,用于将信号分解成多个固有模态函数(Intrinsic Mode Functions,简称IMF)。在MATLAB中,可以使用VMD函数进行信号的VMD分解。VMD函数可以在MATLAB 2020a及以后的版本中直接调用,不过为了兼容旧版本,可以按照"类EMD"的代码风格重新封装VMD函数。VMD函数需要指定一些参数,例如带宽约束因子alpha、噪声容限tau、分解的模态数K等。通过运行VMD代码,可以得到信号的IMF分量,其中u即为分解得到的IMF分量。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
