根据奇异值分解出来的奇异值，画出奇异值分布曲线，根据公式算出奇异值的突变点，此时突变点即是VMD分解分量数的K值(According to the singular value decomposed by singular value, the distribution curve of singular value is drawn, and the mutation point of singular value is calcul

基于遗传算法优化多尺度排列熵参数，类似于粒子群算法优化参数(Optimization of VMD parameters based on genetic algorithm)
