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)

非圆形离散元程序，通过采用非圆形颗粒实现康转动性能(Non-circular discrete element program, through the use of non-spherical particles achieve Kang rotation capability)

常用的积分函数，能够很方便的解决数值积分的问题(Commonly used integral function, can be very convenient to solve the problem of numerical integration)

用于处理信号，对信号进行小波包分解，此处进行了三层分解计算，可以进行迭代。(Used to process the signal, the wavelet packet decomposition of the signal, where the three-tier decomposition of the calculation can be iterated.)

matlab实现捷联惯性导航解算，四元数更新姿态矩阵。(SINS solver matlab)

说明：  彭曼公式主要是计算蒸散发量，在水文和气象中有广泛的应用(Penman formula to calculate evapotranspiration primarily, widely used in hydrology and meteorology)

thermal damage abaqus-umat subroutine

ANSYS 分析一座预应力连续刚构桥的命令流，很实用哦(ANSYS analysis of a prestressed continuous rigid frame bridge command stream, and very practical!)

汽车油耗计算（C实现）对于家用经济型小轿车来说，统计油耗是经常做的一件事。本题目要求根据汽油单价、每次加油所用钱数，以及该次加的油所跑里程数计算出该车的百公里油耗，并进行保存，根据需要给出统计数据。(Vehicle fuel consumption calculation (C implementation) for the household economy cars, the fuel consumption statistics is often one of the things. The questions asked based on gasoline price, amount of money each fuel used, and the second oil added to calculate the mileage run car 100 km fuel consumption, and save, according to the need to give statistics.)

迭代最小二乘法,反演中应用极广泛，非常经典(Iterative least-squares method，An extremely wide range of inversion, very classic)
