一个计算圆周率的自编程序（带原码）。可以计算40000位以内的圆周率。经过充分优化，速度非常快。 开发平台：turbo-pascal 7.0， 嵌入汇编。-a calculation of the ratio of circumference wrote (with the original code). 40,000 can be calculated within the pi. After full optimization, speed very quickly. Platform : turbo-pascal 7.0, embedded in the compilation.

利用C++完成计算方法的分段线性，二次插值和全区间拉格朗日插值的计算！-C completed the calculation method piecewise linear, quadratic interpolation, and the region between the Lagrange interpolation calculation!

聚类算法VC++,可产生随机数，实现了k均值聚类算法和ISODATA算法，可实现样本的载入和聚类，系统在Vc++6平台下运行，有运行的界面和菜单，聚类数目可以人为设定，不同类别以不同的颜色来表示。
