一些关于数学思想应用的matlab代码，以供大家学习分享；(The application of mathematical ideas about matlab code for them to learn to share )

ransac直线拟合：使用ransac方法剔除不好的点，留下好的点做直线拟合，这样拟合出的直线更符合实际，因为没有了错误数据的参与。(ransac linear fitting: Use ransac methods eliminate the bad points, making a good point to make fitting a straight line, so that the fitted straight line is more realistic, because there is no involvement of erroneous data.)

说明：  单悬索采用多次迭代计算的方法 找形-计算 可用于输电线建模分析。(Single suspension method using multiple iterations to find form- can be used to calculate the transmission line modeling)

说明：  基于MATLAB SIMULINK的F-14战斗机俯仰运动仿真，包含风载模型，控制模型等(Pitch motion simulation of F-14 Fighter Based on MATLAB Simulink, including wind load model, control model, etc)

说明：  利用时域有限差分计算电磁场，采用时域算法计算(Calculation of electromagnetic field by FDTD)

说明：  一个机器学习的python文件，里面拥有各种机器学习方法，可以供大家参考(A Python file for machine learning, which has various machine learning methods, can be used for your reference.)

//最小二乘法直线拟合 m_FoldList为关键点(x,y)的链表 拟合直线方程(Y=kX+b) (//linear least squares fitting m_FoldList as the key point (x, y) of Chain fitting linear equation (Y = C/56 b))

本代码可以用于计算特征向量或者矩阵的相似度。(This code can be used to calculate the similarity of the feature vector or matrix.)

一个案例代码，用最小二乘支持向量机的，预测煤炭量(A case code, using the least squares support vector machine to predict the volume of coal)
