HVDC Light连续时间状态空间模型的Matlab仿真(HVDC Light continuous time state space model of the Matlab simulation)

牛顿迭代算法，可以解决非线性优化问题，但是求出的是局部最优解，应用时应该注意(Newton iterative algorithm to solve nonlinear optimization problems, but find the local optimal solution, the application should be noted)

利用小波分析方法进行表面肌肉电信号的时-频率分析，从而得出一系列评价肌肉疲劳的指标(Surface muscle electrical signal when using wavelet analysis method- frequency analysis, to arrive at a series of evaluation of muscle fatigue indicators)

SparseArrays map integers to Objects. Unlike a normal array of Objects, there can be gaps in the indices. It is intended to be more efficient than using a HashMap to map Integers to Objects.
