KIVA 3V的入门介绍

说明：  使用fortran编写的无网格（光滑质点流体动力学）SPH算法(using FORTRAN prepared by the non-grid (smooth particle hydrodynamics) SPH algorithm)

两种涡旋光束的线性强度、强度密度和三维立体图，改变拓扑荷可以改变强度分布。(two kinds of vortex beam)

速度曲线规划，在给定长度path 曲线上，根据各waypoint的速度约束，规划出平滑的速度曲线(speed curve planning.In a given length path curve, according to the speed of the waypoint constraints, planning a smooth speed curve.)

说明：  机器学习的鸢尾花数据集的应用逻辑回归算法分类(Classification of iris data set by logical regression algorithm)

使用梯度下降法、随机梯度下降法和牛顿法实现的逻辑回归算法。(Using a gradient descent method, stochastic gradient descent algorithm logistic regression method and Newton' s method to achieve.)

说明：  蒙特卡罗模拟算法模拟MR模型中有序无序相变(In this cpp, using a useful combined Monte Carlo algorithm, we simulate the MR model model to study the phase transition)

混合高斯模型 对于给定的数据，可以自动选择最佳聚类数目和聚类中心，并根据判决规则进行收敛，运算很快，非常方便(Mixed-Gaussian model for a given data, can automatically select the best cluster number and cluster centers, and in accordance with decision rules convergence, compute very fast, very convenient)

计算地波传输衰减的程序,可以设置高度，大气条件等(Ground wave transmission attenuation calculation program, you can set the height, atmospheric conditions, etc.)

动态CGE模型代码，可以直接粘贴至GAMS软件运行，代码清晰，易于修改。(Dynamic CGE model code, can be directly pasted to the GAMS software operation, the code clear, easy to modify.)

整数位运算及二进制显示。指定整数类型（byte，short,char,int)输入若干整数，选择位运算（&、|、^),显示位运算结果及整数二进制形式(The integer bitwise operations and binary display. Specified integer types (byte, short, char, int) Enter the number of integer bit arithmetic (& , |, ^), showing the result of the operation and integer binary form)
