在原优化算法的基础上，在MATLAB中编程实现了无序碎片跳跃算法（SFLA）。

此程序为奥科AVR开发板的USB实验程序-This procedure for ocote AVR development board

% Function: [class,type]=dbscan(x,k,Eps) % ------------------------------------------------------------------------- % Aim: % Clustering the data with Density-Based Scan Algorithm with Noise (DBSCAN) % ------------------------------------------------------------------------- % Input: % x - data set (m,n); m-objects, n-variables % k - number of objects in a neighborhood of an object % (minimal number of objects considered as a cluster) % Eps - neighborhood radius, if not known avoid this parameter or put [] % ------------------------------------------------------------------------- % Output: % class - vector specifying assignment of the i-th object to certain % cluster (m,1) % type - vector specifying type of the i-th object % (core: 1, border: 0, outlier: -1)

高数矩阵运算代码-high matrix operation code

龙格库塔求解微分方程数值解 工程中很多的地方用到龙格库塔求解微分方程的数值解，龙格库塔是很重要的一种方法，尤其是四阶的，精确度相当的高。此代码只是演示求一个微分方程： 的解，要求解其它的微分方程，可以自己定义借口函数，退换程序里面的函数：

综合了最优化中最小二乘问题的基本经典解法，用C++分别实现了拟牛顿、高斯牛顿、LM三种非线性问题的最小二乘解法，以及基于SVD分解的线性问题的最小二乘解法。
