this is a code for wavelet decomposition

虽然奇异值分解（SVD）和特征值分解（EVD的）是行之有效的，可以通过先进的设施设备先进的算法，它不是通常所说，有一个内在的迹象，可以显着影响的不确定性的结论计算及诠释来自其结果。我们提供一个解决方案，标志模糊的问题确定了从奇异向量的内积和个人数据载体签署奇异向量的迹象。该数据可能有不同的载体，但它有它自身的定位和实际意义的选择方向，其中多数的向量点。这可以通过评估发现了内心的签署标志产品的总和。(Although the Singular Value Decomposition (SVD) and eigenvalue decomposition (EVD) are well-established and can be computed via state-of-the-art algorithms, it is not commonly mentioned that there is an intrinsic sign indeterminacy that can significantly impact the conclusions and interpretations drawn from their results. We provide a solution to the sign ambiguity problem by determining the sign of the singular vector from the sign of the inner product of the singular vector and the individual data vectors. The data vectors may have different orientation but it makes intuitive as well as practical sense to choose the direction in which the majority of the vectors point. This can be found by assessing the sign of the sum of the signed inner products. )

粒子群算法（PSO）的优化程序，通用，很好用的。。(PSO Optimization program)

扭秤法测微小磁场，实验模型需要自己设计。(you can translate chinese into English )

说明：  这是一个建立在OMP算法基础上，笔者自己提出来的一个稀疏分解的DOA估计算法，利用阵列流形矢量间的不相关进行匹配追踪选择，选出与信源位置流形最接近的，以便求得DOA(This is a building based on the algorithm of OMP, the author himself a sparse decomposition algorithm for DOA estimation, using the array manifold a vector between the related matching track selection, and choose the source position manifold closest, in order to obtain DOA)

这是关于数字预失真的仿真程序，应用LMS急降方法实现系数更新，对失真有很好的效果(This is the digital predistortion simulation program, the drop of the LMS coefficient update method implementation, have a good effect on the distortion)

说明：  考察一个长度为 的均直简支梁系统，梁的横截面积为A，弹性模量为E，质量密度为 ，在离简支梁左边支点的 距离和 距离处 施加动态载荷(The mean length of study of a simply supported straight beam system, the beam cross-sectional area A, modulus of elasticity E, mass density, the left away from the simple beam and the distance from the fulcrum of the dynamic loads imposed)
