代码说明：

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)

stock_predicate
matlab 关于股票单项指标滚动预测神经网络源代码。大家可以根据自己的回归预测问题，进行改写，。只用于研究ELMAN神经网络的一般使用，不适合用于投资分析，误差较大，切忌。切忌。(a code of Elman netural network about predicating the stocks price.. it is free and easy..)

Minimum-Bayes-classifier-error-rate
这是模式识别中最小错误率Bayes分类器设计方案。自行完善了在不同先验概率的条件下，男、女错误率和总错误率的统计，放入各个数组当中。全部程序由主函数、最大似然估计求取概率密度子函数、最小错误率贝叶斯分类器决策子函数三块组成。调用最大似然估计求取概率密度子函数时，第一步获取样本数据，存储为矩阵；第二步对矩阵的每一行求和，并除以样本总数N，得到平均值向量；第三步是应用公式（3-43）采用矩阵运算和循环控制语句，求得协方差矩阵；第四步通过协方差矩阵求得方差和相关系数，从而得到概率密度函数。调用最小错误率贝叶斯分类器决策子函数时，根据先验概率数组，通过比较概率大小判断一个体重身高二维向量代表的人是男是女。主函数第一步打开“MAIL.TXT”和“FEMALE.TXT”文件，并调用最大似然估计求取概率密度子函数，对分类器进行训练。第二步打开“test2.txt”，调用最小错误率贝叶斯分类器决策子函数，然后再将数组中逐一与已知性别的数据比较，就可以得到不同先验概率条件下错误率的统计。 (This is the minimum error rate pattern recognition Bayes classifier design.
