这是一个数组练习，程序的作用是查询一个一维数组（数值型数组）中每一个元素出现的次数，且元素出现的顺序不能改变(This is an array of exercises, the program' s role is to query a one-dimensional array (numeric array) in the number of occurrences of each element, and the element can not be changed in order of appearance)

本程序是根据jacobi过关法求实对称矩阵的全部特征值和特征向量(This procedure is based on realistic method jacobi clearance of all symmetric matrix eigenvalue and eigenvectors)

算法优化非常好，几乎没有循环，Relief计算分类权重，包括四元数的各种计算。( Algorithm optimization is very good, almost no circulation, Relief computing classification weight, Including quaternion various calculations.)

遗传算法反演子程序，可用于地球物理非线性反演(The genetic algorithm inversion subroutine, can be used for nonlinear geophysical inversion)

车间调度问题的遗传算法matlab源程序，供大家参考(shop scheduling GA Matlab source for reference)

说明：  基于mises屈服准则的随动强化模型的umat子程序(Follow up reinforcement UMAT)

四阶龙格库塔法，用C++编写，很有参考价值(Fourth-order Runge-Kutta method, written in C, a good reference)

求解流场二维无粘欧拉方程，中心差分，人工耗散(Solving the flow field in two-dimensional inviscid Euler equation, central difference, artificial dissipation)

之前找不到合适精度的log2x函数的定点化源码，经过实现并验证后，发上来大家一起学习(fixed version for log2x)

超级好用的书，面试必备，包括常用的算法介绍，面试题目等等(Super easy to book, interview essential, including the commonly used algorithm is introduced, interview questions, etc.)
