灰色预测模型GM（1,1）算法。
下面举例，一个公司1999到2008年的利润为[89677,99215,109655,120333,135823,159878,182321,209407,246619,300670]，现在要预测该公司未来几年的利润情况。

　　　 在程序中我们仅仅预测该公司10年以后的情况，数据可修改，把(n+10)里的10改成你需要的数字即可。(The grey prediction model GM (1,1) algorithm.
For example, a company's profit from 1999 to 2008 is [8967799215109655120333135823159878182321209407246619300670]. Now we need to predict the profit of the company in the next few years.
In the program, we only predict the company's situation 10 years later. The data can be modified to change the 10 in (n+10) to the number you need.)
