Recursion and iteration are two very commonly used, powerful methods of solving complex problems, directly harnessing the power of the computer to calculate things very quickly.
This iteration calculation formula possessed properties including fast convergence, high accuracy and convenience for use, and can be operated through computer program.
此迭代法求解公式不仅收敛快，计算精度高，应用方便，而且可供计算机程序求解。
