一种有效的降维方法的源代码，原始的，可以很方便的改进。(it is easy to understand, monifoid leaning)

说明：  对sinc函数进行内插后的误差比较（matlab）(Of the sinc function interpolation error after the comparison (matlab))

在数学规划，尤其在数学建模中，很好用,可以参考(In mathematical programming, especially in mathematical modeling, easy to use, you can refer to)

说明：  分变模态分解（Variational Mode Decomposition，VMD）是一种具有坚实数学基础的分解算法，能够通过建立约束变分模型表达式，将信号以非递归的方式自适应地分解为若干本征模态分量(Variational Mode Decomposition is a decomposition algorithm with solid mathematical foundation. It can adaptively decompose signals into eigenmodes in a non-recursive manner by establishing constrained variational model expressions.)
