hybrid fusion of multi sensors navigation

修改后的phase函数，把它的门限值换为pi，使用更方便(The modified phase function, the threshold for it to pi, the use of more convenient)

code can used for determining correlation value to analyze rho based on s11, s12, s21, s22.

本程序利用改进的支持向量机理论进行混凝土抗压程度预测，取得了较好的效果(This procedure using improved support vector machine (SVM) theory to carry on the concrete compressive degree prediction, good results have been achieved)

探讨了在 MATLAB 环境中实现遗传算法仿真的方法 ,并以一个简单的求函数最值的问 题作为遗传算法的应用实例 ,说明遗传算法的全局寻优性及用 MATLAB 实现仿真的可行性(Explore the genetic algorithm simulation in MATLAB environment, and the value of a simple demand function as genetic algorithm application examples, description of the genetic algorithm global optimizing nature and the feasibility of using MATLAB simulation)

说明：  自编多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscaleSampleEntropy函数中的SampleEntropy也可以单独拎出来计算单个样本熵。(Multi scale sample entropy is used for a section of bearing fault data, which is easy to understand. SampleEntropy in the MultiscaleSampleEntropy function can also be picked up separately to calculate the entropy of a single sample.)
