Geochem 数据集基本统计参数计算
- 数据集基本统计参数计算，例如平均值、均方差、最大值、最小值、1/4分位值、2/4分位值、3/4分位值、峰度系数、偏度系数、异常下限等。使用迭代算法实现。-A program for statistic parameters from a dataset, such as the means, STD variation, MinX, MaxX, 1/4 quatitile, 2/4 quatitile, 3/4 quatitile, Kut. and Skew. coefficients, th
sushu
- 使用Eratosthenes算法编写程序，求20000以内的素数，每隔500为一个测试点，每个测试点计算五次，记录每次的运行时间求平均值，结合计算机硬件配置以及运行时间随数据规模的增大的变化情况分析计算机性能。-To write programs using the Eratosthenes algorithm, find the prime numbers less than 20,000, every 500 to a test point, the calculation for each
