Blei 03年lda实现

计算器源代码c。和windows自带的功能差不多。很多科学计算还没有加入。-c source code calculator. Windows and almost onboard functions. Many scientific computing has not joined.

求解对角线元素很小的矩阵的逆矩阵,避免一般求逆的溢出问题,用Fortran编写-small diagonal elements of the matrix inverse matrix inversion generally avoid the overflow problems, Fortran prepared

子集和数问题，回溯法实现-subset of several problems that back Method

决策树是用二叉树形图来表示处理逻辑的一种工具。可以直观、清晰地表达加工的逻辑要求。特别适合于判断因素比较少、逻辑组合关系不复杂的情况。 -Decision tree is a tree-shaped diagram used to indicate the processing logic as a tool. Can be intuitive, clear logic processing requirements. Particularly suited to determine the factors that have relatively less logical combination of relations with complex situations.

c语言简单算法实例-c algorithm example, simple language

改进的背包问题：给定一个超递增序列和一个背包的容量，然后在超递增序列中选（只能选一次）或不选每一个数值，使得选中的数值的和正好等于背包的容量。 代码思路：从最大的元素开始遍历超递增序列中的每个元素，若背包还有大于或等于当前元素值的空间，则放入，然后继续判断下一个元素；若背包剩余空间小于当前元素值，则判断下一个元素

黄金分割的程序实了例，求COSX的最大值-0.618 process does the cases, seek the maximum COSX
