symMat
A matrix of symbolic elements is reasonably useful for many analytic linear algebra applications, and for analytic vector, matrix and tensor differentiation.
This function produces a matrix of arbitrary dimension of symbolic elements that are indexed by their position in the symbolic matrix for ease of reference.
EXAMPLE
>> M = symMat([2 2], m , real )
M =
[ m11, m12]
[ m21, m22]
>> class(M)
ans =
sym
>> det(M)
ans =
m11*m22 - m12*m21

一种自适应算法 local-mean-decomposition
2005年J.S.Smith提出的局域均值分解LMD(Local mean decomposition)的原始文献，该方法可用于故障诊断、特征提取、振动信号分析等多领域，是较EMD更为温和的一种自适应算法，目前是热门研究方法。(This is the original article about LMD——Local mean decompositon. Ihis method is a novel adaptive decomposition. It is more better than EMD and achieve more and more attention.)

DFT
自己实现的一维、二维DFT。优点：变换后的低频分量在中间，弥补了matlab库函数的不足（高频分量在中间）(Realize their own one-dimensional, two-dimensional DFT. Advantages: low-frequency components after the transformation in the middle, made up for the inadequacy of matlab library function (high-frequency component in the middle))
