Newton-raphson-method

本程序主要根据有限元法编写，可以求解薄板的振动和静力分析问题(This procedure mainly based on the preparation of the finite element method can solve the plate vibration and static analysis of the problem)

求解指派问题，再输入指令后，根据信息自动快速的求出最佳分配方案(Solve the assignment problem, and then enter the command, according to the information automatically and quickly find the optimal allocation scheme)

ITD方法分析 需要自己输入数据，如模态阶数、采样频率等-ITD analysis needs its own input data, such as the modal order, the sampling frequency, etc.

钢管问题。最优话模型求解。易拉罐，最优采购！(matlab pipe problem. If solving the optimal model. Cans, the best purchase!)

基于matlab的约束非线性规划算法库，适于学习！(Matlab-based algorithm for the constrained nonlinear programming library, suitable for learning!)

近似熵是一种衡量衡量非线性时间序列复杂性的非线性动力学分析方法，其物理意义 为熵值越大，时间序列的自我相似性越低，序 列越复杂，反之序列自我相似性越高；并且样 本熵对于序列长度依赖弱，仅需较短的数据就 能够得到稳健的熵值，同时其计算不需对数据 粗粒化，具有较好的抗干扰能力 (Approximate entropy is a measure to measure the complex nonlinear dynamics of nonlinear time series analysis method, the physical meaning of entropy value is larger, the lower the self-similarity of the time series, the more complex the sequence, whereas sequence of self-similarity the higher and the sample entropy weak dependence for the length of the sequence, only shorter data can be healthy entropy value, calculated without data coarse-grained, with good anti-jamming capability)
