circular calculation的用法和樣例：
例句
- Base on the calculation of numerical value, an iterating method on calculating quick initialization is put forward.
基於數值計算提出了一種計算快速起步的迭代方法，分析並採用迭代方法進行了起步計算。 - Secondly, the method applies a linear iterative procedure in calculation and the SVD is used as a main tool, avoiding complex nonlinear optimization processes.
實現過程是以奇異值分解為基本工具的分步線性迭代計算，避免了傳統射影重建方法複雜的非線性優化環節。
