实现softmax的多分类

说明：  利用非线性动力学的知识研究混沌行为，可以通过画运动的分岔图来研究参数变化对运动的影响，本程序以洛伦兹力为例子实现了分岔图的绘制(Knowledge of the nonlinear dynamics of chaotic behavior, can 通过 Painting Movement of the bifurcation diagram to study the impact of parameters on the movement, this program in order to achieve the Lorentz force as an example of bifurcation diagram drawing)

对于周期图的功率谱估计,当数据长度N太大时,谱曲线起伏加剧, 若N太小,谱的分辨率又不好,因此需要改进。两种改进的估计法是 平均周期图法和平滑平均周期图法。Bartlett法:Bartlett平均周期图 的方法是将N点的有限长序列x(n)分段求周期图再平均。(For the power spectrum estimation of the periodogram, when the data length N is too large, the spectral curve fluctuation intensifies,   If N is too small, the spectral resolution is not good, so need to be improved. The two improved estimates are   Average Period Graph and Smooth Mean Period Graph. Bartlett method: Bartlett average cycle chart   Is to re-average the finite-length sequence x (n) of N points by periodogram.)
